Fix local model validation error for Ollama models

[roomote]

Fixed false validation error when using local Ollama models. The validation logic was checking against an empty router models object placeholder, causing incorrect errors even when models existed locally.

Now only validates against router models if they actually contain data.

Fixes ROO-581
