Two runs of the same programme can produce different machine code from the JIT compiler, unless everything in the universe that happened in first execution run, gets replicated during the second execution.

Do these compilers sometimes give correct instructions and sometimes incorrect instructions for the same higher level code, and it's considered an intrinsic part of the compiler that you just have to deal with? Because otherwise this argument is bunk.

That’s 100% correct, but importantly JIT compilers are built with the goal of outputting semantically equivalent instructions.
And the vast, vast majority of the time, adding a new line to the source code will not result in an unrecognizably different output.
With an LLM changing one word can and frequently does cause the out to be so 100% different. Literally no lines are the same in a diff. That’s such a vastly different scope of problem that comparing them is pointless.
