According to #213 there is eg. k3s crictl ps for low level access to the containers,
but when I run that command, it always returns No help topic for 'crictl'.
Am I doing something wrong?

I also tried the k3s binary from the website and that one worked fine.
So I guess crictl is not bundled with the k3s that is packaged on openSUSE tumbleweed.

Yeah I'm not sure who packaged that version, but it's not a build that's produced by us. I suggest using a release produced by this repo, as opposed to the one packaged by OpenSUSE. It also appears to not set the version properly:

Open a ticket in openSUSE Bugzilla, describe the problems there and we will fix it.
