When he came out talking about allowing LLM code contributions everyone told him this would happen.

He has criticized the excessive hype around GenAI/LLMs long before. Torvalds has generally a very pragmatic approach, not a black-and-white one.

Three things more:

The Linux kernel is Torvalds project.

The fact that experienced kernel developers can sometimes use LLMs to their advantage does not mean that the average Joe Codemonkey can do it. These algorithms are often described as a kind of competence multiplicator - but experience from education shows that they are more risky than that and can hinder learning.

And third, we should in this question not put too much weight in the opinion of influential people. Behind the GenAI tech are huge corporations which pour billions of money into it. It is likely that they can pressure and bribe people and that they also pay influencers and bloggers to tout their stuff. Making decisions dependent on single influential persons, however competent and acclaimed they are, is therefore dangerous (see Eric Raymond, Eva Kaili or Gerhard Schröder). Torvalds is not Jesus, and I am pretty sure he didn't apply for that role.
