Construct an OpenAPI agent from an LLM and tools.
Security Note: When creating an OpenAPI agent, check the permissions
and capabilities of the underlying toolkit.
For example, if the default implementation of OpenAPIToolkit
uses the RequestsToolkit which contains tools to make arbitrary
network requests against any URL (e.g., GET, POST, PATCH, PUT, DELETE),
Control access to who can submit issue requests using this toolkit and
what network access it has.
