The use of LLM agents was allowed relatively recently, you still have 20 years of guaranteed no llm commits in the history. As for personal LLMs being the cause of the traffic, I think you are overestimating the number of users of LLMs generally, and even then most of those users are not actually developers. And there are even fewer cases still where the llm being used actually needed something from the linux kernel, personally after quite heavy use of LLMs on linux, I have never seen it try to fetch the linux kernel directly once.
