Orchestrate Workflow with Lindy and Langsmith Observability

Design an integration with Lindy to orchestrate the FOIA request processing. Based on the classification from OpenAI o4-mini, trigger different Lindy workflows (e.g., 'SpamWorkflow', 'LegitimateReviewWorkflow'). Additionally, integrate Langsmith to trace each step of the AI classification and workflow execution, capturing model inputs, outputs, and tool calls for auditing purposes. Describe how you would set up the Lindy API calls and Langsmith traces.
