Maybe - I think my friend's friend is more in the giving nuanced advice space of accounting rather than anything too mathematical.

I know accountants, most of the stuff they deal with is getting stuff to make sense when your dealing with an unreliable narrator dealing with push back from their employers and then attempting to synthesize a coherent narrative over a large corpus of heterogeneous internal documents, controls, spreadsheets and legal agreements. LLM’s as they exist now are yes men, they are not good at making coherent fact patterns, especially when someone pushes back on them or gives them a red herring or mis-represents something. There’s a long list of things that need to improve for them to gain traction in that industry.
