How to replace Message a Model?

Questions
1

So I finally figured one workflow on my own

But I would prefer to use ollama instead of OpenAI
via Credential I have OpenRouter and my own Ollama which both works
where I get stuck is how could I message a model and with which nodes.

I tried these nodes AI Agent but it doesn’t offer the same JSON output as messaging a model via OpenAI.

Does anybody know how to easily replace Message a Model of OpenAI node?
