If you enable lingering for a user, it's the "systemd --user" instance (i.e. the per-user service manager) that is started at boot and terminated at shutdown (instead of started at first login and terminated at last logout of the user), that's all. If you then run code as user service (i.e. as a service started and managed by the "systemd --user" instance instead of PID 1) then it is lifecycled (and its processes killed as needed) by the user service manager. And you can configure the way you want killing to behave like you would for any systemd service: with KillMode= in the unit file.
