>So you are presenting the fact that lawyers must digest an absurdly large corpus of legal documentation, but also maintaining that is something a human lawyer has some sort of advantage over a LLM?

No.

A LLM has more opportunity itself to replace a Lawyer, the person typing the prompt is not necessarily required to be as educated. Though a case can be made that you need to validate the information.

As it happens we have an opportunity to tell how this works. Software engineering has seen many abstractions of which each comes with its own complexity in verification.

What tends to happen is that people don't really do a lot of verification, we are just "mostly right" very fast and leave an immense amount of inefficiency and indirection behind us.
