I could be wrong, but I think Jellyfin has an option to give something a sort name. So while it would display the Italian name it would be sorted alphabetically by the name you type in.
This is so movies will be sorted in order. I’m not sure if it will work, but please give it a try and let us know.
That’s a cool feature. I doubt the app would offer this as they probably do not want to allow the notifications to be turned off.
