hello and welcome to the forum,
those flags should not affect rclone lsf, as that list files, does not transfer them,
and from that link you shared
so i think your command should have been
rclone lsf --onedrive-list-chunk, not rclone lsf --onedrive-chunk-size
as a test, i might create a new dir and copy the files into the new dir.
and then run rclone ls on that new dir.
and if that works, try rclone copy/sync
