With a real lawyer almost all the time what they tell me will be legally correct, so if I don't know how to recognize when something is not legally correct that will almost never hurt me.
From what I've seen of people's posts of ChatGPT output it is much more likely to provide incorrect legal advice, and so using it without having a way to recognize incorrect legal advice is much more likely to hurt me.
You can't sue OpenAI for giving you really bad advice because they're not a law firm.
Also in the UK, for example, lawyers can't hide behind a limited liability company, they have to have skin in the game.
i.e. you can sue them personally for negligent advice and in theory they could loose everything they own (barring tools of the trade and bedding).
You can't do that to anyone that works at OpenAI Incorporated just because their language predictor convinced you of something that wasn't true.
Even if they were based in the country you could only sue the corporation.
