Add AI Chat Orchestration to call APIs

# Why?

**As a** user

**I want** to be able to write out a prompt and have AI interpret what I want to do

**So that** I can more easily call APIs

# What?

Implement LangChain, with whatever OpenAI model is free.

https://js.langchain.com/docs/how_to/tool_calling

# Additional context

Can just call APIs directly from library.
Ideally, the chat will confirm with the user before making a API call.

Don't want AI to directly manipulate the database. Want to have at least the APIs to constrain what it's able to do.
