relevant issue for the lib: Kakulukian/youtube-transcript#11
It is mentioned about ip bans but it never worked for me from the start but worked with other library

I also do have a solution. Swapping the library 'youtube-transcript' to 'youtubei' fixes the issue but i am not sure if this is a good solution as i am not sure if this library is maintained. Also only tested locally so far i dont know if there will be different issues on cloud env.

LibreChat\api\app\clients\tools\structured\YouTube.js

const { Client } = require('youtubei');

// replace line 166
const client = new Client();
const video = await client.getVideo(videoId);
const captions = await video.captions.get('en');
return parseTranscript(captions);

We can't enable transcripts if they are disabled, and I was unaware we could work around it to get the captions. This seems hacky and is not officially supported by YT: https://stackoverflow.com/a/73290079

You shouldn't need to swap the library for this, as you could take a look at how the library does it. PRs welcome.

So according to youtube api you should not be able to get them if you are not the owner of the video. The library does a hack around it, it seems as you say.
