I made the same choice for our stack last year.

We initially had problems diagnosing issues inside LangChain and were hitting weird issues with some elements of function calling, so we experimented with a manual reconstruction of exactly what we needed and it was faster, more resilient and easier to maintain.

I can see how switching models might be easier using LangChain as an abstraction layer, but that doesn't justify making everything else harder.
