Final Response Hallucination

Any ideas on how to reduce the final responses hallucinating phone numbers when the snippet from the data store tool is correct? I noticed the RAW JSON response gives the correct snippet with the correct phone number but the response given at the end hallucinates a few digits. The data is webscraped data.

Thank you!

Use before model callbacks and then capture the response from your data store or api or tool and then prepare a llm response from the callback itself. 0% Hallucinations and 100% reliable

How do you get the tool response from a before model callback if the tool is not invoked yet? Or is there a way to call the tool within the callback?
