None of my installations have ever had anything installed in /var/at except empty directories, so I don't think there's anything in the base installation user "at" and therefore started by atrun. Like user crontabs, users can be allowed or denied the use of "at". The general impression one gets from reading the "at" manual page is that it may be useful for running some resource-intensive routines at specific times or times when resource use is low; but I think cron and crontab are more familiar to most people and more flexible, so atrun and at have fallen into dissuse. I suppose (if you really cared) you could disable atrun in crontab and find out if anything quits working, but somewhere there could be a script you expect to work that uses "at" and therefore depends on atrun.
