Given the fact that all lat-tools perform sysadmin tasks (create users, groups, etc), they must be run as root. I suppose a workaround would be to use sudo, but I haven't tested this.
Coming to think of it, it's probably much cleaner if non-root users aren't even allowed to start the lat-tools. Now users are confused if the tools don't seem to work because of they're not root. I'll see if I can do something about that for the next release.
