Routing by itself is solved problem, there is no need for AI here. But! AI could be used to look at datasheet of the part and identify the signal. Typical status LED or power good signals do not care about routing while power and high frequency signals are very sensitive to the routing.
That doesn't seem hard for the PCB designer to simply specify when designing. Although, I don't know how to design PCBs so I may well be missing something.
