launchd
I sometimes encounter various tasks for com.apple.xpc.launchd in the system logs that give errors like Service only ran for 0 seconds. Pushing respawn out by 10 seconds. or Service exited with abnormal code: 78, etc.
How can I find and remove these services? It seems that they are not listed by traditional tools that I've seen and used so I'm not sure where they may be enumerated to the system to try to initialize and thus how to disable them…
It really depends on why you care (inherently, you shouldn't, or more likely, there's some better way to do it). It all comes down to your script being smarter. Drop a turd file or use the script to either defer until next run, or go into a holding pattern.
You can send to Notification Centre using Applescript (osascript )in you shell script.
There is a very good thread here that explains the various ways of either running only Applescript as a shell script or being able to mix applescript in with bash, for example.
I created a shell script with:
#!/bin/bash
theDate=`date '+DATE: %m/%d/%y TIME:%H:%M:%S'`
osascript -e "display notification \"$theDate\" with title \"test 1\" subtitle \" sub 1\""
I then created a LaunchDaemon in the same way you have and loaded it without sudo.

Every 90 seconds I get a notification:
The notification icon you will notice is the Script Editors one. Which means the Notification is controlled by the Script Editors Notification settings in Notification Centre

XPC Services
XPC services are low level components within applications. They are not designed to be managed by the user and can not be individually disabled without breaking applications:
As an example, Safari.app's XPC services are stored within:
Report problems to the developer
In many cases, an XPC service behaviour is controlled by Apple's
launchdimplementation. Expect different behaviours for the exact same service between major macOS versions.If there are specific XPC services causing serious problems, please tell the associated developer, be that Apple or a third party developer.
