I believe the torrent included both an .mkv and a malicious .lnk file.
.lnk files are dangerous because they can evade detection and automatically open other files or executable on a computer; AFAIK you would not have had to open the .lnk file yourself.
It depends on the attack vector. Typically you’re right, but malicious .lnk files are often paired with other malicious methods to infect machines. Sometimes they’re configured as a worm that copies and spreads when a flash drive is connected, sometimes they’re configured to download a remote payload when another script or program is started. The problem is that it’s a type of file that’s often overlooked because it seems innocent.
It isn’t necessarily the case that the Trojan needs to be interacted with by the user in order to execute the malicious code. Just having the file on your machine opens the door for all kinds of attacks (especially if you’re using a headless setup: you wouldn’t necessarily know you have the .lnk file in the system unless you’re manually unpacking your downloads yourself). All it needs is for another piece of infected code to run and look for that file, and it can open the door for more traditional malicious code.
Edit: just as a for-instance - If I was a black hat and wanted to spread some malicious code, I could include this .lnk file in a torrent (innocuous enough to slip by unnoticed by most people/unscrupulous pirates), and then maybe place a line of code in a jellyfin plugin or script that looks for that file and executes it if it’s found. Because the attack isn’t buried in the plugin or script itself (most people wouldn’t think much of a line of code that’s simply pointing to temp file already on your system), it could theoretically go unnoticed for long enough to catch a few hundred or thousand machines.

Wait, what? A .lnk file is a shortcut… you still have to click those for them to open whatever they’re pointing to.
