I used langchain in one project and I do regret choosing it over just writing everything over direct API. I feel their pain.
It had advantage of having standardized API, so I could switch local LLM to OpenAI and just compare results in a heartbeat, but when I wanted anything out of ordinary (ie. get logprobs), there was just no way.
