Looks like a normal comment to me, what makes you think otherwise? It has pretty much no hallmarks of being generated, and plenty that point towards the opposite.

Quoting the user it’s replying to in third person, and then hallucinating words inside the quote.

When I have asked LLMs to read/dictate a linked text, the output is usually not a clean read but something reinterpreted with its own style.

Starting the comment pointing out the name of the user you're replying to, and quoting the exact comment you're replying to, does sound really strange.
