StructuredLLM examples have ValidationError

[averikitsch]

All tutorials that use StructuredLLM or llm.as_structured_llm() are not currently running. They experience the following error:

ValidationError: 1 validation error for StructuredLLM
output_cls
  Input should be a subclass of BaseModel [type=is_subclass_of, input_value=<class '__main__.ReportOutput'>, input_type=ModelMetaclass]
    For further information visit https://errors.pydantic.dev/2.9/v/is_subclass_of

These tutorials are also missing a pip installation step. The tutorials only installs the observability dependecy "llama-index-callbacks-arize-phoenix".

They work fine for me with latest versions of things.
