[FEATURE] Create example of Ollama agent in examples folder

[og-hayden]

Problem Statement

There is currently no file in the example directory showcasing using ollama to power Legion agents.

Proposed Solution

We need a simple example file, with one or two tools, and some basic message sending. Like in examples/agents/basic_agent.py

Alternative Solutions

n/a

Additional Context

This ticket has a dependency on getting the Ollama provider fully tested and working in all four modes of operation.

Implementation Ideas

Benefits

Helps developers interested in using Legion with locally running models see how to do it with agents.

Potential Challenges

When using small local models like llama3.3 8b, things like tool use (more broadly function calling) isn't nearly as accurate, so there may be erroneous issues not by fault of the code, but rather by the hardware limitation of the computer running it.
