I hate to say this, but it actually IS your problem, not theirs, if you don't meet other requirements after you've completed the program. They aren't going to run criminal background checks on every applicant and I seriously doubt they will be held liable.
Regardless, you need to check with the State licensing board in Ohio to see if your criminal history DOES disqualify you automatically.
Frankly I think you have an uphill battle on your hands - your attorney is apparently asking you for something that doesn't exist, and you're probably going to find that the school has all kinds of disclaimers.
What's perhaps more important though is that to discharge loans in bankruptcy, they must meet the Brunner standard - and that has nothing whatsoever to do with your situation. It's purely about hardship, not about whether you think it was unfair of the school to accept you or not.
