In commercial law, the business model is to rent the associates out to clients at rates higher than you pay (d/t your supervision). No client will pay $350/hour for your AI.
And for direct billing, it's not your interest to do things faster for the client (at risk of making a mistake).
So the real question is whether these pay-by-the-hour models will die as a result of competition from fixed-price transactions made viable via automation. I think not because the entire difficulty of legal work is that it's a complex bundle of issues until you sort them out; once sorted, there's really little to do other than execute (read: paralegals).
But they may be willing to pay $200/hour for your AI (plus, of course, your final expertise in the matter as the lawyer), and the firm can ditch the paralegals and pocket the difference.
The point is, if you need fewer grunts doing the busywork, you can charge less and be competitive.
But they already do! There are cases of professional service firms creating their reports using LLMs, there have even been a few prominent scandals re the fake data generated in them
Whether everyone at the labs knows it or not, this it what they are doing to entire industries, starting with software: Embrace, extend, and extinguish

What a time to be alive!!?
There will still be jobs for competent associate attorneys to prompt LLMs and review output. But frankly a lot of attorneys — especially many of those who attended "Third Tier Toilet" (TTT) law schools — were always a waste of money and should have never entered the profession in the first place.
