Is it possible to use the "test level" button and start up a level without bots? I usually need to kick them every time I start up a level since I wanna test without them shooting at me

Start your UT99, then go to UT Menu -> Multiplayer -> Start New Multiplayer Game -> Bots, set "Min.Total Players" to zero, and press Start to start the game.
Set up this once UT99 should remember this after restart, also started by the editor.

I don't think it needs to be multiplayer , just start new game , set bots in menu to zero, or how many kills, or time limit. etc etc

You can bind "killall bot" or "killall bot|killall bots" or "killpawns" to a key and use it everytime you want to start the match without them.
