This is a prime example of a problem space where accuracy matters, but it also matters who ultimately goes to prison. I'm going to go out on a limb and guess it's not the LLM.
If you're acting in good faith and your accountant does something crazy or evil, your liability is limited to some extent. You may get a tax bill but you're probably not gonna end up behind bars. But if your LLM decides to do a little bit of tax fraud, you're in uncharted waters. In the end, the gun did it, but you were the one holding the gun.
A lot of jobs are like that. You're not as much buying the service as you're buying not having to worry about the service.
