If even you, who probably could look at the full source code, cannot tell "why the heck would anyone want that in an Access app", how can people who cannot see this code guess why one wanted it?
I understand that you badly need some resolution, but could you be a bit more realistic. Can you contact the original authors? If not, and the code is really bad and not properly documented, it could be possible that the value of this code is very low, if not negative. There is no such thing as miracle. There are many cases when people eventually had to write some project from scratch, despite the desperate attempts to reuse the code. If you really face "the bunch of morons" (I cannot be 100% sure, but think it would be reasonable to assume that you are right), you should also understand that trying to get something useful from such a "bunch" could be just a wast of time. If you face that, you should also face the reality.
Maybe you would be interested to know that the autocorrect feature was always problematic in Access? Please see:

I don't believe someone can help you with much more than that. :-(
