run cmd will do it, just fire a trace to see if they have an enemy targeted and then fire another to aim for head and see if that shot is valid, and adjust angles. you can do most with getclienteyeposition/angles.

something like so
check if bot has in attack button
get eye pos, eye angle, fire ray
test if ray hits an enemy
get enemy eye pos and angle
fire a ray to enemy
if ray hits, set eye angles so the bot uses the ray angles
