I think youtube might be your best bet unfortunately.
The issue is that I don't think that kind of info is surfaced in the API, so someone manually has to enter it somewhere and sites like light.gg aren't going to do that. The D2 community overall seems to be taking a break right now too.
This community is relatively new and small and I think our engagement with the game will pick back up at the new season and TFS so you might see more content like that on here come then.
