### What happened?

Hi, our LiteLLM proxy logs are full of `INFO` lines for each request. We'd like to switch that off. We expect `LITELLM_LOG=ERROR` to do the job, but it does not help.

Here is a minimal example to reproduce the problem:

`litellm_config.yaml`:

```yaml model_list: - model_name: gpt-4o-mini litellm_params: model: openai/gpt-4o-mini api_key: sk-[...] general_settings: master_key: sk-1234 ```

run:

```bash docker run \ -v $(pwd)/litellm_config.yaml:/app/config.yaml \ -p 4000:4000 \ --env LITELLM_LOG=ERROR \ ghcr.io/berriai/litellm:main-v1.69.0-stable \ --config /app/config.yaml ```

When sending requests like this

```bash curl -X POST 'http://0.0.0.0:4000/chat/completions' \ -H 'Content-Type: application/json' \ -H 'Authorization: Bearer sk-1234' \ -d '{ "model": "gpt-4o-mini", "messages": [ { "role": "user", "content": "Hi." } ] }' ```

the LiteLLM proxy server [logs](https://gist.github.com/Dobiasd/294a5857453a7c67ab54143d3514faa5) lines as follows:
