Feature request

Currently it's not possible to use the node_properties or relationship_properties when calling LLMGraphTransformer with Ollama or ChatOllama. This results in an error message
The 'node_properties' and 'relationship_properties' parameters cannot be used in combination with a LLM that doesn't support native function calling.

I don't believe Ollama supports native function calling for now, but may be there is a way around that?

Motivation

Ollama at equal llevel to OpenAI for langchain
