There's a lot of missing information for anyone here on Trulia to give you a much better answer than this, and there's at least two sides to every story. The majority of smart/active agents do maintain Errors and Omission insurance.
You might also want to contact the Georgia Real Estate Commission and ask them the question, trust me they'll take it very seriously.
Just in case you want to hear from a non-real estate agent, each of the two answers below is correct:
No one here can really answer your question, other than to tell you anyone can sue anyone. The real question is: do you have a case that will convince the arbitrator/judge/jury you are correct?

Find an attorney that works in the real estate field and spend some money if you want the real answer.
