Basically, do you want a pipeline/process that utilizes LLMs and provides exactly the output you want? How do you formalize a human expert workflow using LLMs? With LLMOps. It is new, there is no standard or predefined resource that I'm aware of. At neuralnetes we are creating all of our methods ad hoc and use tight feedback loops to ensure ideal, precise output.
No need to set impossible standards here, the correct thing to ask is whether the guardrailed LLM confabulates less than its competitors. That sounds like a useful job to have.
