You need to do it manually in that case.  This is an example with a
whole disk encrypted guest:

guestfish [--ro] -d Guest
><fs> run
><fs> vfs-type /dev/vda1 
ext4
><fs> vfs-type /dev/vda2 
crypto_LUKS
><fs> luks-open /dev/vda2 encrypted
Enter key or passphrase ("key"): 
><fs> vgscan 
><fs> vg-activate-all true
><fs> list-filesystems 
/dev/vda1: ext4
/dev/vg_f13x64encrypted/lv_root: ext4
/dev/vg_f13x64encrypted/lv_swap: swap
><fs> inspect-os 
/dev/vg_f13x64encrypted/lv_root
><fs> inspect-get-product-name /dev/vg_f13x64encrypted/lv_root
Fedora release 13 (Goddard)
><fs> inspect-get-mountpoints /dev/vg_f13x64encrypted/lv_root
/: /dev/vg_f13x64encrypted/lv_root
/boot: /dev/vda1
><fs> mount /dev/vg_f13x64encrypted/lv_root /
><fs> mount /dev/vda1 /boot
><fs> edit /boot/grub/grub.conf
