No, the discussion is about whether validation is certain to happen when the LLM makes something where the frontend recognizes aa a tool request and calls a tool on behalf of the LLM, not whether the LLM can choose not to make a tool call at all.
The question is whether havign observed Claude Code validating a tool response before handing the response back to the LLM, you can count on that validation on future calls, not whether you can count on the LLM calling a tool in a similar situation.
I think the others are trying to point out that statistically speaking, in at least one run the LLM might do something other than choose to use the correct tool. i.e 1 out of (say) 1 million runs it might do something else
