It's still a loss in torque though, which itself isn't doing the fuel
mileage any favors.

Again, you're still conflating torque with energy.

Not one reference shows an increase in mileage other than stating that, in
"some cars" the torque curve will be put in a better spot but "most cars"
won't.

The reality is that it seems the variables I tried to keep out of the
original question (for example tire width, tread pattern, rubber material,
inflation pressure, unsprung weight, etc.) can make more of a difference
than does the larger diameter tire.
