An llm can, by understanding some features of the input, predict a categorisation of the input and feed it to do different processors. This already works. It doesn’t require anything beyond the capabilities llms actually have, and isn’t perfect. It’s a very good question why this hasn’t happened here; an llm can very reliably give you the answer to “how do you sum some data in python” so it only needs to be able to do that in excel and put the result into the cell.

There are still plenty of pitfalls. This should not be one of them, so that’s interesting.
