Root Cause: python client is using item.xx https://github.com/llamastack/llama-stack-client-python/blob/main/src/llama_stack_client/lib/cli/models/models.py#L54-L59 to get those values, but actually those values are in item.metadata, this only impact CLI but not models.list() API, so all integration test still works as they are not using llama-stack-client CLI but API call.
