Without specifying what you want to do, it's a bit like asking which kitchen knife you should buy. I think they are all relatively convoluted but can help with some boilerplate, but most of the magic is the llm itself. Setting up a vector search is not that complex, but langchain has many premade connectors for a POC. I personally haven't seen many actual production usages (or heard of) people really using the auto part (i.e. llm -> llm -> llm feedback loop). It looks cool in theory but has many issues that make it impractical and too expensive imo.
