The useful question is not whether to use AI. It is which parts of a job need judgement, and which parts just need moving accurately from one place to another.
Reading a messy invoice or a scanned form. Sorting incoming email by what it is about. Drafting a first reply for a person to approve. Pulling the relevant clause out of a long document.
Anything that has to be exactly right every time with no human looking. Moving a number between two systems is plumbing: deterministic, testable, boring. Using a model there adds cost and a failure mode you did not have before.
Anything that goes out under your name, moves money, or cannot be undone gets a human approving it. That is a design rule here, not a setting we might turn off later.
