Link to Issue or Description of Change

• Closes: Allow openai 3.x in the openai extra (currently openai>=2.20,<3) #8099

google-adk[openai] currently caps the OpenAI SDK below 3, which blocks installation with recent versions of LiveKit Agents. This raises the cap to <4 in the openai, extensions, all, and test extras while keeping the minimum at 2.20.

Testing Plan

Unit Tests

• I have added or updated unit tests for my change.
• All unit tests pass locally.

The OpenAI integration and labs tests passed on Python 3.13 with SDK versions 2.54.0, 3.0.0, and 3.46.0 (296 tests each).

I ran the full Windows tox suite on Python 3.11 through 3.14 using the upstream CI dependency skip for lancedb. Each run passed more than 23,800 tests and had 88–104 failures outside the OpenAI and packaging tests. Most failures also occurred on unchanged main. The remaining SQLite and telemetry cases passed in focused reruns on both branches. Both branches resolved the same test dependencies.

Manual End-to-End (E2E) Tests

I built the ADK wheel and installed its openai extra in clean Python 3.13 and 3.14 environments alongside openai==3.46.0, livekit-agents==1.8.11, and langfuse==5.2.0. The same install failed to resolve before this change. With the new wheel, uv pip check reported compatible dependencies and all 296 OpenAI integration and labs tests passed against the installed wheel on each Python version.

To reproduce the dependency check from this checkout in a clean environment, run:

uv pip install '.[openai]' 'openai==3.46.0' 'livekit-agents==1.8.11' 'langfuse==5.2.0'
uv pip check

Additional context

The constraints check reported the same differences on Windows for both this branch and main. The resolved package pins matched main for Python 3.11 through 3.15.
