Remove Literalai dependency

[KoenDesplenter]

Describe the bug
A clear and concise description of what the bug is.
Chainlit still depends on the literalai dependecy which has become non updatable and so it needs to be removed. Subdependencies of literalai are stale and prevent newer versions of langchain of being installed.

The following packages are incompatible
├─ chainlit 2.10.1** is installable and it requires
│ └─ literalai 0.1.201.* , which requires
│ └─ traceloop-sdk >=0.33.12 , which requires
│ └─ opentelemetry-instrumentation-langchain [0.38.8 |0.39.1 |...|0.53.3.* ], which requires
│ └─ langchain >=0.3.15,<0.4.0 , which can be installed;
└─ langchain 1.2.7** is not installable because it conflicts with any installable versions previously reported.

To Reproduce
Steps to reproduce the behavior:
Install the packages with the version as shown above.

Expected behavior
A clear and concise description of what you expected to happen.
The installation of chainlit and langchain to succeed.

This is a known issue. literalai is currently a hard dependency pinned to literalai==0.1.201 in Chainlit's pyproject.toml, so there's no way to install Chainlit without it.

LiteralAI integration was marked as deprecated with a removal date of October 31, 2025, but it remains a hard dependency in the package. Your specific conflict (literalai → traceloop-sdk → opentelemetry-instrumentation-langchain constraining langchain <0.4.0) has been reported in similar forms in issues like #1627 and #2188.

Current workarounds:

• Downgrade to a langchain version compatible with the constraints (<0.4.0)
• Wait for the maintainers to remove literalai as a dependency

This should probably be tracked as a feature request to fully remove the literalai dependency now that the deprecation deadline has passed.

To reply, just mention @dosu.

Is there any ETA to remove this dependency?

This was partially resolved by @hayescode by relaxing dependency versions in #2881 and the rest is in #2892 now
