Grub doesn't support LVM RAID1 (it supports only RAID 4/5/6 type IIRC).
However, I don't recommend using /boot on LVM at the moment since
grub support for LVM is limited and unofficial. There's a plan to add
official and more robust support though - there are ongoing discussions
between grub and LVM team...
