This feature predates LLMs though, right? Funnily enough, I actually find it hilarious! In my mind, once they introduced it, it immediately became "a list of things NOT to reply if you want to be polite" and I was used it like that. With one exception. If I came across an update from someone who's a really good friend, I would unleash full power of AI comments on them! We had amazing AI generated comment threads with friends that looked goofy as hell.
LLM dates back to 2017, Google added that to internal gmail back then. Not sure when linkedin added it so you might be right, but the tech is much older than most thinks.
