That's weird - is there nothing that can help you in Settings > Accessibility? There should be an option to answer calls with the Volume Up physical key.
An alternative would be to use a compatible walker case, and answer calls by opening the case. However, I can appreciate that if you have limited dexterity a wallet case might cause you more faff.
It'd be a weird part of the UX for LG to mess around with for no good reason. Maybe the carrier faffed with it?
