Yes Partition alignment in kickstart is possible. To change the start sector from 63 to something like 128 or  similar check the below example kickstart script.

clearpart --none
part /boot --fstype ext3 --onpart=sda1
part pv.01 --onpart=sda2
volgroup myvg pv.01
logvol / --fstype ext3 --name=lv_root --vgname=myvg --size=4096 --grow
logvol swap --fstype swap --name=lv_swap --size=512 --vgname=myvg
