How can I set-up OCLP BootLoader(EFI) on Linux?

I've never installed a Linux distribution on any machine before, but I was curious about Arch Linux and its customization flexibility. Yesterday, that curiosity got the better of me, and I decided to set up a dual-boot Arch Linux with my OCLP (OpenCore Legacy Patcher) Ventura system. I knew I shouldn't mess with the OCLP bootloader, but during the installation process, I accidentally formatted /dev/sda1, the partition containing the OCLP bootloader.

However, after about 15 failed Arch Linux installation attempts, I somehow managed to avoid erasing /dev/sda2, which holds my OCLP Ventura system.

I need to access my important files, cookies, and projects from macOS, but I can't boot into it. I also don't have a separate Mac to create and copy the bootloader from.
