How can I edit this script not to kill AIs of each team?

How can I edit the script to insert a condition that checks for example the torso colour or a value inside the team ai so that it does not damage a team ai? I've already dealt with it killing team members but now i need to change it so it doesn't kill team ais as well. I'm not sure how to identify where to insert the line of code that checks the value inside the character. I think the main problem is that the script checks if it is a player or an ai it is damaging. I think I'm probably inserting the line of code in the wrong place. Here's the main part of the hit script. The script's quite long but I would really appreciate it if anyone could help me and tell me how to identify where to insert the script for future reference when I want to do the same for other weapons.

    if not humanoid or humanoid.Health == 0 or not torso then
        return
    end
