> My point was that you can have very well designed and thoughted apps with LLMs.

If that were the case here, then a user of the app probably would not come away with the impression that it was a "very much LLM-aided app."

You're talking about how LLMs can be used in such a way that they help production of an app but remain invisible to the end user. But the beginning of this thread was someone using the app and coming away with the impression that it was heavily LLM influenced, which suggests that it was not done thoughtfully and did not remain invisible to the user.
