I mean, I don't know.. those quotes seem way too clean from what I'd expect of normal people chatting. Also the use of em-dash. Does it say somewhere that it's an LLM that has compressed the sentiments of the conversations to create these quotes? I wouldn't be surprised if it was.

Even pre-AI, it was common to “massage” genuine quotes like this so they read better.

Hell, anyone who’s been interviewed by a journalist can tell you they do it, too, sometimes to the point of changing the substance of what you said.
