Why is that something to hold against LLMs? They're making a ton of progress and will probably significantly improve the productivity of e.g. paralegals. The fact they're not legal persons and our rules against unauthorised practice of law mean they're not going to be in courtrooms any time soon even if hypothetically they were twice as good as defense attorney work (they aren't, right now). A technology can be really impressive and indeed revolutionary without making literally every job redundant. That seems like an absurdly high bar to hold anything to.
