When I had to implement "deidentification" for a kind of sensitive safety reporting, an LLM would've been a good way to augment the approaches I used.

Today, if I had to do it, I'd probably throw multiple computer approaches at it, including LLM-based one, and take the union of those as the computer result, and check it against a human result. (If computer and human agree, that's a good sign; if they disagree, see why before the document goes where it needs to be deidentified.)

(In some kinds of flight safety reporting, any kind of personnel can submit a report about any observation related to safety. It gets very seriously handled and analyzed. There are also multiple ways in which the reporting parties are protected. There are situations in which some artifacts need to have identifying information redacted.)
