Description

What happened?

The ollama_chat_client.py sample passes tools as a direct keyword argument to OllamaChatClient.get_response(), but the method doesn't accept tools directly. It should be passed inside the options dict.

What did you expect to happen?

The sample should run successfully and return the current time using tool calling.

Steps to reproduce the issue

1. Set OLLAMA_MODEL=llama3.2
2. Run: uv run python/samples/02-agents/providers/ollama/ollama_chat_client.py
3. See TypeError

Code Sample

Current broken code (lines 43 and 48 in ollama_chat_client.py):

# Non-streaming (line 48):
response = await client.get_response(messages, tools=get_time)

# Streaming (line 43):
async for chunk in client.get_response(messages, tools=get_time, stream=True):

Should be:

# Non-streaming:
response = await client.get_response(messages, options={"tools": get_time})

# Streaming:
async for chunk in client.get_response(messages, options={"tools": get_time}, stream=True):
