Amazing how someone with your experience can have such poor reading comprehension. He never said anything about permission to use llms. They are saying that to a domain expert like you, you can effectively use LLMs because you will be more likely to spot issues and thus guide it better given your background in the domain. He is saying that some biz bro who know nothing about docusign and esigning who decides one day to use LLMs to create software in that domain is likely to produce working, but buggy and non-compliant software.

As a non expert in a domain, LLMs can seem amazing because you don’t know the field therefore have a harder time spotting errors. As an expert they seem pretty dumb or they’re useful as long as you guide them. It’s akin to Cory Doctorow’s argument about the reverse centaur.
