Assuming your account is an Admin one, not a Standard account (in System Settings > Users & Groups), I think

	sudo rm -r /var/root/Library/texlive

would have have worked in Terminal. I cannot check though.

But otherwise, you're right: in the Finder you can see the content of /var but you can't see the content of /var/root, even less get inside to put drag /var/root/Library/texlive to the Bin. I had forgotten about that.

To see what's there, you need to use Terminal again, for example

	sudo ls -l /var/root
	sudo ls -l /var/root/Library

As revealed by "ls -l /private/var", /var/root has permissions

	drwxr-x---    13 root          wheel           416 Aug 21  2022 root

meaning it is owned by user "root" of group "wheel". Only members of this group have the "x" bit set for it, meaning they can "execute" the directory /var/root to get inside it.

Your account most likely belongs to the "admin" group. For /var/root this means it is of the "other" category, hence has rights --- that is not "r" for read neither "w" for write nor "x" for execute.

sudo allows you to temporarily impersonate the root user, for one command only.
