Two problems

[Storfigge]

For problem number 1, you could always set the chasing Grunt(s) to inactive after you don't need it anymore, and set a new one active in its place which isn't chasing the player if you're afraid for whatever reason the player might backtrack his tracks, and discover that it has vanished.

Example:

SetEntityActive("grunt_9", false);

I want those to be "true" because if I die I want them to respawn.
