So let me get this right: if RTAI is used it will spawn kernel threads that inherit cgroup membership of the client requesting it? That realls sounds like a kernel issue to me, and should be fixed by RTAI. I mean, I have no idea what this really is and how it behaves, but allowing kernel threads to live in arbitrary user managed cgroups sounds a bit dangerous to me... That all said, you can use KillMode= and related settings to alter what is killed. See systemd.kill(5) for details.
