Seems like they still don't get it.
It's not good faith representation of your client, it's not good lawyering to interrogate a chatbot for your case. Even if it could somehow only ever tell the truth.
It's not a "good faith mistake" - so I think they still don't understand the problem here.
It might be representative of greater society: when people interact with ChatGPT, they treat it as an oracle. I see it all the time on r/chatgpt - people say, "I asked ChatGPT about my long lost grandparent whose life I am researching. Apparently my grandma was a pilot!"
Seems like the lawyers are shocked the oracle lied but still think they were right to consult it.
