Chances are it could be Telltale Games who designed Tails Doll. While tails Doll still has a place in Sega lore, I think the reason why we never see Tails Doll in modern era of games could be legal catches with Tt, that or Sega simply have no use for him.

Anyway the reason why Tales Doll was made for Sonic R was to be both unlockable character and robot counterpart to Tails. Metal Knuckles also debute in Sonic R for being the robot counterpart to Knuckles. A standard EggRobo was chosen as Dr. Robotnik's robot counterpart.

I guess the reason why Tails' counterpart isn't "Metal Tails" is because the developers couldn't really imagine a bad@$$ robo'mofo to match with adorable sidekick Tails (Though Archie Comics did introduce the Metal Series with Metal Sonic and Metal Knuckles reprising their role decades later on). A life-size plush toy does seem to match Tails cuddly apperance.

The whole "Tails Doll Curse" is purely fan speculation cooked up from those who found Tails Doll more crepy than cute and doubt was intended at al by Tt Games.
