How confident are you that yourcore.imgis built to support reading from LVM? I know you're not getting as far as failing to boot, but the problems may well be related.

Absolutely not confident. It's created during initial installation of Arch using the Antergos installer. I can see that GRUB loads the lvm module so that may be a good sign..

After some extra-extra reading on the Arch forums I've added lvm2 to mkinitcpio.conf under HOOKS.
HOOKS="base udev autodetect modconf block keyboard keymap encrypt resume lvm2 filesystems fsck"
And then I ran again:
mkinitcpio -p linux
systemctl enable lvm2-lvmetad.service
grub-mkconfig -o /boot/grub/grub.cfg
But this didn't change anything.

I've created a manual Grub config in 40_custom and this almost works. The LVM is found and luks on root is decrypted but then I get this error:
Begin: Running /scripts/init-bottom ... mount: mounting /dev on /root/dev failed: No such file or directory
done.
No init found. Try passing init= bootarg.
Then I'm left with command line: (initramfs) _
Manual GRUB config:
menuentry 'Kali' {
insmod lvm
insmod gzio
insmod part_msdos
insmod ext2
set root=lvm/triagia-kaliboot
search --no-floppy --fs-uuid --set=root f1eb6904-c17e-40b7-8740-60e67b8d04de

}

How confident are you that yourcore.imgis built to support reading from LVM? I know you're not getting as far as failing to boot, but the problems may well be related.

Absolutely not confident. It's created during initial installation of Arch using the Antergos installer. I can see that GRUB loads the lvm module so that may be a good sign..

You will need to add the kernel parameter in order for GRUB to decrypt the disk so that it can load your kernel.
Add command below into GRUB's kernel parameter:
cryptdevice=UUID=device-UUID:lvm root=/dev/mapper/MyVol-root
The <device-UUID> refers to the UUID of /dev/sdaX
Decrypt and then boot, that's it.
For more information, please refer to Arch Wiki.
