Would it be possible (and food safe) to fill the voids with some sort of hard epoxy, then sand flat and wipe with butcher block oil? If this idea is food safe I’d prefer this route verse basically throwing all that work away. Or mayb use it as a checker/chess board or just to hang on a wall and look at

It would both possible and food safe to fill the voids with epoxy. The catch is that it would negate the desired aspects of an end grain board. The patch would not accept the usual mineral oil and wax finish and would stick out like a sore thumb. End grain boards are “friendly” to scoring by knives from use. Cutting across the grain on long grain boards leaves more damage. Most knives wouldn’t dent a chunk of hardened epoxy so the patch would be more apparent with time. I just wouldn’t do it. Make it a serving tray or something like that and it would be OK, but I wouldn’t do that either. It sounds like the OP was able to find a way to cut the flaw out to make a smaller board. I would do that.

Wood is a natural material that comes with natural defects. You have to plan for the occasional natural flaw when planning a project. When you purchase rough sawn / dried stock for a project you have to be prepared for a hidden defect in the stock when you joint and plane it into the desired dimensions. Same goes for the thicker pieces used to build cutting boards, even if they have been prepped from the rough sawn state. You really need to be prepared to deal with natural flaws in the stock.
