It's because things change, things break, they are misconfigured etc. Yes, if you have perfect deterministic tools in an unchanging and perfect environment, sure. But the deterministic tools need constant maintenance, fixing, reconfiguring, adapting to external changes, dealing with unexpected failure types etc. Not saying you should use LLMs for everything, but LLMs equipped with tool calling can often fix things. And they can also fold it back to a robustified script. That's the strongest use case. LLM checking errors, fixing the scripts, and the routine runs are via those scripts. It just checks that everything ran to completion or what kind of hiccup happened. I know this sounds terrifying from a job security perspective, but it's going to be a wild ride for all of humanity.
