[Bug]: model_name and token_usage not returned in callback when invoked via agent

[nitin302]

Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

traceloop/openllmetry#2166 has code example and more details which confirms this is a bug in langchain code.

Error Message and Stack Trace (if applicable)

No response

Description

I am using langchain to invoke agents via agent_executor.invoke with Azure Open AI. However, model_name and token_usage is not returned via callback. This is required to send telemetry via openllmetry.
