example of using an LLM

• extremely simple
• uses VSH component for MVI (minimum viable implementation)
• needs to be improved for production
• note: to run this, you must set the environment variable OPENAI_API_KEY to your openai key (put a few $s into your account and generate a key, or, rewrite the command in the main component to use some other LLM)
• this version based on Emil Valeev's project "Agency" (written in Go)
