zfs-initramfs, along with zfs-dkms and various other packages, are arch:all and
thus should be installable normally with apt if you added the sources entries
like I said. It's only the userland tools and libraries that come as
arch-specific packages and therefore needed to be built by you.

That looks normal; the i386 build log shows the same thing.

Do you know which you're using? I believe switching to grub is as simple as:
1. apt install grub2
2. grub-install --skip-fs-probe --force /dev/sdX
though it's been a while since I had to deal with that process.
