[Feature Request] Automated Integration of LlamaIndex with Langfuse for Enhanced Observability

[hongsw]

Is your feature request related to a problem? Please describe.

Integrating LlamaIndex with Langfuse for observability currently requires manual code implementation, which can be time-consuming and prone to errors.

Describe the solution you'd like

An automated integration between LlamaIndex and Langfuse that simplifies the setup process, allowing developers to achieve observability with minimal configuration. Utilizing Langfuse's LlamaIndexInstrumentor for straightforward initialization would be ideal.

Describe alternatives you've considered

Manually coding the integration, which increases the risk of inconsistencies and maintenance challenges. Exploring other observability tools was considered, but Langfuse's features align better with our requirements.

Additional context

Langfuse's official documentation provides examples for integrating with LlamaIndex. Implementing an automated integration based on these guidelines would enhance developer productivity.
