THEN Modify `convert_to_ollama_tool` in `ollama_functiony.py` to handle tools with `args_schema` attribute. When a tool is a StructuredTool, extract the schema via `tool.args_schema.schema()` and build a definition with name, properties, and required fields, rather than raising ValueError.

if hasattr(tool, 'args_schema') and tool.args_schema is not None:
    schema = tool.args_schema.schema()
    definition = {'name': tool.name, 'properties': schema['properties']}
    if 'required' in schema:
        definition['required'] = schema['required']
    return definition
