Linus Torvalds is OK with vibe coding as long as it's not used for anything that matters

I get your argument just fine, and as I said I think you have a very credible and interesting point regarding the fact that LLM outputs are a nondeterministic abstraction. But if you consider LLMs as an abstraction in generating code, why not humans?? I don't see the principled distinction, as human devs are also code generators.
This is sensible in practice, since if someone needs to build something, they can either hire a dev or they can vibe code it themselves. Either way, they will end up with deterministic code (albeit perhaps very different quality depending on the code generator).
