Add a mkdir in your %post. For example:

 %post
mkdir -p /etc/sddm.conf.d/
cat <<FOE > /etc/sddm.conf.d/autologin.conf
[Autologin]
User=live-user
Session=plasma.desktop
FOE
%end

(I'm assuming your config would work once the directory exists. This
at least fixes the post error in your kickstart)

Can authselect help here?
