No, absolutely the opposite. LLMs are terrible at things that require judgment and justifications, because they don't reason. They come up with something that sounds plausible.

That's not good enough when you're dealing with matters that can lead to civil or even criminal liability. Errors can be incredibly expensive to fix, if they can be fixed at all.

With a CPA or attorney, you at least have recourse if they screw up. You don't with LLMs.
