First - I am not a lawyer - just getting that out there.

So dropping the live image type avoids the first set of issues.

Is your target system using legacy PC BIOS or UEFI?

If UEFI, then you can specify EFI_PROVIDER = "gummiboot" and use that
instead of grub-efi as gummiboot is LGPL v2.

If you are using PC BIOS, have you considered not using grub at all and
just relying on syslinux, GPL v2 or later.

Grub-install is a nightmare in my experience, and doubly so in atypical
environments as you describe. Without a lot more diagnostics, straces,
etc, I can't offer much advice.

Which device are you attempting to install grub to?

Same version of Grub?
