[AI] Export data as sentences digestible by LLM

[yuripourre]

The current data model is very flexible but there is no intuitive way to access the data.

One way to have it and also make it more future-proof is generating human-readable sentences that can be used as input to LLM-based chatbots like ChatGPT.

We need to iterate over the model and extract leafs until the root node so order makes sense.
