libVLC is experimental and not well supported in Jellyfin. Personally, it's only caused problems so I force exoplayer only.
Regarding AV1 and exoplayer, what I am hypothesizing is happening is that something about your video file is not supported by your device (audio codec or container). The problem is that the output of a remux or audio transcoding would be in the TS container and TS does not support AV1 necessitating a video transcode to H264.
Jellyfin 10.9 will support remuxing to fMP4 which will allow remuxing while retaining AV1.
