United States v. Heppner mentioned a public chatbot service. If a law firm (or specialized provider) offered a chatbot using their own servers and hosted the traces and other data on the law firms own servers it would almost certainly be protected. But another case would need to happen to determine that.

But that only applies for clients using the chatbot. If a lawyer is using the LLM it is definitely protected. No different if a lawyer searches something on Google or Lexis Nexis. The search itself is protected. I guess you could debate metadata but the content surely is protected.
