This 15" MacBook Pro mid-2014 was DELIBERATELY bricked by my son's disgruntled girlfriend putting a random, and forgotten, BIOS password on it. We don't have proof of purchase and cannot get it. Are there any other fixes? I've heard that there's a hardware fix?

The only way is to remove the firmware chip and re-burn it with a clean image and remount it.
This is quite advanced as you need good micro soldering skills and access to a ROM burner and a clean image file and have the skills to edit the image with the systems S/N otherwise any software which is keyed to it will fail.
It might be cheaper getting a replacement system (used - the same model) then you can just swap over the SSD drive and be back in business (that is if the files are intact and not encrypted.
这个答案有帮助吗？
I do wonder what Apple would do, if I could ever convince them to do it. I can't see their techs doing that level of work. Maybe that's why they make you jump through so many hoops.
@vwalton Apple themselves have access to tools/applications that removes the need to physically remove and reflash the ROM.
Maybe you could just get a replacement SSD and get an external enclosure? https://eshop.macsales.com/shop/ssd/owc/...
@vwalton & @geirandersen - In this case they won’t even try as this is no longer a supported system 😞
And if you can’t prove you are the true owner forget it!
@danj Indeed! I’ve even heard horror stories from users that had physical proof (digital and original receipt) and Apple tried stalling 🤔 BTW @danj, why did you remove your cool avatar?
@andrewsawesome, new disk & enclosure won’t do anything as the firmware is locked on hardware level (ROM) on the logic board.

Shut down your mac. Now power up your Mac and immediately start holding the Command and R keys. Do you see anything on the screen?

Yes, I see the firmware password prompt. That's the problem.

@vwalton Have you tried putting in your user password at the prompt?
