## Description

The LiteLLM Docker image (including latest v1.86.2) still ships with **ddtrace 2.19.0**, which breaks the \`/embeddings\` endpoint entirely when APM tracing is enabled on Python 3.13.

This was originally reported in #8744, but that issue was auto-closed as stale without a fix.

## Root Cause

\`ddtrace==2.19.0\` has a bug in its function bytecode rewriting that causes a \`coroutine already executing\` error when \`AsyncOpenAI\` client is reused on Python 3.13. This affects all Azure OpenAI and OpenAI embedding models going through \`/embeddings\`.

The fix was released in **ddtrace==2.19.2** (DataDog issue: https://github.com/DataDog/dd-trace-py/issues/11994).

## Affected Versions

Confirmed broken: v1.83.7-stable through **v1.86.2** (latest as of 2026-05-29)

```sh # Verify ddtrace version in current image: docker run --rm --entrypoint /bin/sh ghcr.io/berriai/litellm:v1.86.2 \ -c "/app/.venv/bin/python -c 'import ddtrace; print(ddtrace.__version__)'" # Output: 2.19.0 ```

## Steps to Reproduce

1. Run LiteLLM v1.86.2 with `USE_DDTRACE=true` and `DD_APM_ENABLED=true` 2. Send any request to `POST /v1/embeddings` with an Azure OpenAI or OpenAI embedding model 3. O…
