Usually they would just use an off the shelf product and extend it, so they wouldn’t produce the absolute horror story described in the article, no.
I’m not even sure what your last comment means, are you contending that it is a good thing this company violated multiple laws with sensitive patient data?

AI does the same thing an agency or dev would do. Those vibe coding platforms have a template for these things which is usually Vite + React with Supabase for the backend, the same as a dev might use because surprise the LLM trained on the dev's work.
OP's point is that you're not guaranteed a good outcome hiring an agency or solo dev either, in fact I would say you're almost guaranteed a bad outcome either way.
Apparently your assumptions about AI are completely wrong, if you read the article it produced terrible code.
