I use a local llm provider for opencode, I can run it 
`opencode run -m litellm-poc/qwen3_5-122b 'ping'
`

but iteratr reports errors below:

```
Iterationloop failed:failed to start KIT agent:failed to initializeKIT SDK:failed to create agent:failedto
create/agent:failed to create model provider:unsupported provider:litellm-poc （not found in model database). 
```
