We've had success with non-developers using some of the visual tools built on top of LangChain to build exploratory models in order to prove a concept. LangChain does seem well suited to providing the "backend" for that type of visual node-based modelling.
Of course, once the model is proven it is handed off to developers to build something more production-worthy.
