You are still dodging the question -- what is the problem with not being able to determine in advance what the LLM will do?

Even then, you can clearly see that the LLM will try its best to follow the instructions. The result might not be 100% predictable, but it is somewhat predictable depending on the task.

After the LLM does what it has been asked, you can review it, iterate on it, test it, and so on. And if you're trying to make anything worthwhile, you will do so.

Lack of determinism is not a practical concern.
