My efi partition was overwritten by mistake and now I can't boot into KaOS. I was dual booting KaOS with Arch and both their bootloaders were deleted by mistake. I have managed to reinstall arch's grub but now I don't know how to install KaOS systemd-boot. Anyone to assist?

Not clear what you need, once you have the grub bootloader on one distro, you can add any other to it.
