/**
 * @deprecated Use non-OTEL `wrapAISDK` from `langsmith/experimental/vercel` instead.
 *
 * Initializes OpenTelemetry with LangSmith-specific configuration for tracing.
 *
 * Call this once at the start of your application to enable tracing integration. Sets global
 * OpenTelemetry components including the tracer provider and context manager.
 *
 * Requires the following peer dependencies to be installed:
 * - @opentelemetry/api
 * - @opentelemetry/sdk-trace-base
 * - @opentelemetry/exporter-trace-otlp-proto
 * - @opentelemetry/context-async-hooks
 *
 * @param options - Configuration options
 * @param options.globalTracerProvider - Optional custom TracerProvider to use instead of creating and globally setting a new one
 * @returns Object containing the initialized OTEL components (tracer provider, span processor, exporter)
 *
 * @example
 * ```typescript
 * import { initializeOTEL } from "langsmith/experimental/otel/setup";
 * initializeOTEL();
 * ```
 *
 * @example With custom tracer provider
 * ```typescript
 * import { initializeOTEL } from "langsmith/experimental/otel/setup";
 * import { BasicTracerProvider } from "@opentelemetry/sdk-trace-base";
 *
 * const customProvider = new BasicTracerProvider();
 * initializeOTEL({ globalTracerProvider: customProvider });
 * ```
