OpenAI outright says it will give your conversations to people like lawyers.

If you thought they wouldn't give it out to third parties, you not only have not read OpenAI's privacy policy, you've not read any privacy policy from a big tech company (because all of them are basically maximalist "your privacy is important, we'll share your data only with us and people who we deem worthy of it, which turns out to be everybody.")
