Again, from the local US Embassy website:
 
 

No... you are wrong. If you read what I shared:
 

Sounds like the wife had 2-yr green card and you let it lapse. If that’s the case, the only thing you can do is start again with I-130. 

Here you go
https://www.uscis.gov/i-407

Submit I-407 to nearest international USCIS office. If you are in Thailand, it's the Bangkok office: https://www.uscis.gov/about-us/find-uscis-office/international-offices/thailand-uscis-bangkok-field-office

The tourist visa application is stand-alone based on your circumstances at the time of application.
My experience, and we lived overseas for 7 years after K3/AOS, is that your attorney is correct.  I did not see that non-USC spouses had any difficulty getting tourist visas for trips back to the US with their spouse nor was being married to a USC who was working and living overseas seen as a hurdle.  In fact ties to the USC’s job and home there seemed to be considered strong.
I knew many, many American expats and I never saw one non-USC spouse turned down.
I also had no difficulty myself when we re-filed a new petition to return back to the US when / if you get to that point.  Good luck!
 

WOW. So many people concerned with the OP's life choices. Life happens. Life CHANGES. My husband and I would be happy living in the states, OR in Sweden - we picked the states for various reasons. But us settling down here never ruled out Sweden completely, and I would never pass up any better opportunities that may arise for either, or both, of us down the road that would lead us to Sweden. Doesn't mean we never wanted to live in America or regret our decision to do so now. I highly doubt there's anyone who would spend the time - and money, most importantly - to settle down in the US unless that was the best option for them AT THAT TIME. Geez Louise.
 
OP - I echo what others have already said. It's definitely not impossible to be able to return to visit, for your wife, but COULD pose as difficult. Regardless of past situations, I think the bottom line, for any visitor visa, is being able to support and prove ties to the foreign country. So, property in her name, a solid job, etc. Reasons for her to return, and reasons negating possible intent to immigration at the time of visiting. PAST intent of immigrating (that was willingly forfeited with good reason) wouldn't necessarily be a negative deciding factor, in my opinion, so long as other required criteria to balance it out is met.
 
Good luck to you and your wife on your new adventure and careers! Safe travels.

Why does it matter to you? We moved to America because we wanted to. And now we are moving back to Thailand because we want to.

We did almost the exact same thing.   We got the K-1, and then relocated temporarily to the USA and got married while in the 90 days.   Before the 90 days expired we had the opportunity to return to Hong Kong..   My wife with a Philippine passport had previously been denied a tourist visa for immigrant intent.  After 3 months back in Hong Kong she went for a tourist visa Interview and was quickly and easily granted the visa.  Seems that my Residency in Hong Kong with full local employment became her strong tie and her previously going thru the process and giving it up apparently was sufficient to convince the officer of non-immigrant intent.   I have no idea if we resided in the Philippines or Thailand and done the interview there if it would have made a difference.... However,  in my opinion she has a strong chance of gaining a tourist visa if you have valid residency and strong reason to remain in Thailand

Thailand has a 20% refusal rate for tourist visas as of last year. This may not sound too high, but it is on the higher side of things (very similar to the Philippines and such). Strong ties will be needed.
 
The property is good, but certainly doesn't guarantee anything...one an always sell that after coming to the US.
The car is very likely not considered a tie at all.
Employment is good, although this also depends on the nature of the work and such. Some jobs are easier to leave than others. How long one has been working there is also a factor.
 
That said, there are many, many people with stable jobs and a house that are denied a tourist visa due to 214b (immigrant intent). Having a USC spouse and previous AOS application are negative factors regarding immigrant intent.
 
But only way to know is when you are ready to apply.

In fairness to the OP.....rereading the thread, it is more clear that the "she has no intent to live here" part was in reference on how to prove that to POE (if intent is perceived to stay and adjust status) at a later date when returning to the US for tourism purposes.  Not in reference to having "no intent" when K1 and AOS was previously filed for:
 
OP is basically saying their lawyer advised that surrendering/withdrawing the AOS is a way of (hopefully) showing no intent to stay and adjust status when crossing in the future as a tourist, if intent is brought into question at POE.
 
OP, keep in mind that entry is only guaranteed to US citizens---with a US spouse, and having had immigrant intent before, expect some level of scrutiny at the border for your foreign spouse.
