Tied EC is certainly not 0%. You can construct a couple different plausible scenarios.
Trump 2020 + GA, NV, AZ, NE-2

Trump 2020 + PA, MI (I also swapped NC and GA, but that makes no difference)

Probably others. That was just playing around for a minute or two with the map.
I am curious why you think these are exceedingly unlikely?
