I guess the STTY special environment variable has no effect if
interactive is not set.

Why not simply:
stty -onlcr
in your script?
If you're worried about resetting the terminal state on exit (which
you shouldn't in a zpty session), you always can:
savedstty=''
trap 'stty $savedstty' EXIT
savedstty=$(stty -g)
stty -onlcr
