Well that depends on what kind of "illegally" he came in on. If he crossed a fence or got smuggled in, that's entry without inspection and milimelo is right - that's a showstopper: no AOS for you.
If he came in on some kind of short term nonimmigrant visa and vanished into the crowds, that's a different story. He's still just as illegal, and it's still a flagrant violation of the law, but visa overstays are generally forgiven (or perhaps it's more accurate to say the law mandates no non-waiverable penalty) for immediate relatives of US citizens.
Overstaying a visa, marrying a USC, and adjusting status is far from unheard of, and while it's illegal, dangerous (in terms of possible life disruption if caught), and massively inconvenient, it is doable. Entering without inspection, on the other hand, just totally screws up any realistic chance of ever normalizing your status, pretty much forever (or at least until you return home, serve out your 3 or 10 year bar, and reenter under a legal status).
Don't deal with it. Leave her be. When she is done sulking, she will talk again. Don't reward passive-aggressive childish behavior with undue attention and it will lessen over time.
Fix it by ignoring it.
Feed it by paying attention to it.
