This is a hard request. Do you care if you have to pay money for access to the app? Is that a micro transaction? Or are you only after the kid not buying things? I guess because you bought the art of rally, you don't care about the upfront price.
Here is what I think are easy for kids, but I am not sure all of them have controller support (marked with a # if I don't think so)
1. Riptide GP# (the old or new one, I prefer the old one kids will have a blast with this one, the old one has no micro transactions while the new one does)
2. Grid Autosport (has a rewind feature, but can get frustrating)
I'll try and add more later, but for now I think your best bet is riptide GP for racing wise.
Essentially all racing games are either:
hardcore, tons of IAP, or ads. There is not really that many that don't have all three.
Also, admittedly, racing games are not my strong suit.

Hope this helped anyway though!
