For the inventory, you could do something like this (untested, but should work in theory)
if victim's inventory contains armor:
As for the Enderchest/PVs, I'm not quite sure, since Skript does not have integration into the plugin Personal Vaults (as far as I'm aware).
For Enderchest, you are using a Custom Enderchest plugin, which likely creates a Custom GUI and completely replaces the default Enderchest, so Skript's Enderchest support would not function for it.
I do not know quite what to do for the PVs and EnderChests, but hopefully the inventory bit helps!
