I don't know how it is in other countries, but in the UK using LLMs for any form of paid legal services is hugely forbidden, and would also be insanely embarrassing. Like, 'turns out nobody had any qualifications and they were sending all the work to mechanical Turks in third world countries, who they refused to pay' levels of embarrassing.

I say this as someone who once had the bright idea of sending deadline reminders, complete with full names of cases, to my smart watch. It worked great and made me much more organised until my managers had to have a little chat about data protection and confidentiality and 'sorry, what the hell were you thinking?'. I am no stranger to embarrassing attempts to jump the technological gun, or the wonders of automation in time saving.

But absolutely nobody in any professional legal context in the UK, that I can imagine, would use LLMs with any more gusto and pride than an industrial pack of diarrhoea relief pills or something - if you ever saw it in an office, you'd just hope it was for personal use and still feel a bit funny about shaking their hands.
