Is there launch control? I don't know if there is
if not this is a good suggestion for the next update

There isn't really a launch control in this game. All you have is traction control

Also traction control(TC) does not work on all wheel drive(AWD) cars.
Hopefully this get fixed soon.

What cars have traction control?

Can't really name them all, but many in S2 and much more in S3.

is there any in s1?

Hmm, not sure man, I'd say probably no cars with TC in S1.

ı guess FZ5,LX6,GTR cars and formula
( maybe RAC )

Only two official LFS cars have traction control - the FZ5 and BF1:
