Grub only needs to know about the filesystems that it uses to boot the system. Mounting of the other file systems including /var is the responsibility of the system that has been booted. I suspect that you have something else wrong if you can't boot with /var/ on ZFS. I may be wrong, but I don't think so. If grub needed to know about the file systems other than the one it is using to boot, then it would have parameters to describe the other file systems.
