If my phone is not powered on on my K30 would androids shutdown monitor still show on the Google activity list?

Welcome to Android Central! Shutdownmonitor is a system app, so there's nothing shady about it, in case you were worried.

When you say "not powered on," do you mean you completely powered the phone off, or just put the screen to sleep?
