When removing a torrent with “Also remove the content files” instead of deleting the files it moves to .Trash-ID, even on headless/docker systems.
Set to delete files: Settings -> Advanced -> Torrent content removing mode: Delete files permanently

PS: There’s a pull request to revert back to delete https://github.com/qbittorrent/qBittorrent/pull/21528
You apparently have little interaction with regular users because one of the top problems a non-power user has is “oops I accidentally hit delete on this important file I don’t have a backup of”.
Not saying qbittorrent-nox of all things switching makes a ton of sense but at least for desktop applications there is a very good reason why deleting things becomes a two step process.
