> there's no good way to do LLM structured queries yet

Because LLMs are inherently designed to interface with humans through natural language. Trying to graft a machine interface on top of that is simply the wrong approach, because it is needlessly computationally inefficient, as machine-to-machine communication does not - and should not - happen through natural language.

The better question is how to design a machine interface for communicating with these models. Or maybe how to design a new class of model that is equally powerful but that is designed as machine first. That could also potentially solve a lot of the current bottlenecks with the availability of computer resources.
