maybe i should have given more details about my suggested solution.

create your partitions as usual, but create one partition big enough to
store all your encrypted data:

/dev/sda1 -> /boot
/dev/sda2 -> all encrypted data

encrypt the desired partition:

cryptsetup ... create encrypted-sda2 /dev/sda2

put LVM on the encrypted device:

pvcreate ... /dev/mapper/encrypted-sda2
vgcreate ... encrypted-volume /dev/mapper/encrypted-sda2

create your logical volumes for your encrypted needs:

lvcreate ... --name encrypted-root encrypted-volume
lvcreate ... --name encrypted-swap encrypted-volume

now you are able to add a single entry into crypttab while having
multiple logical volumes encrypted
