Do symmetrical airfoils generate induced drag?
If an airfoil is producing lift, then it will be producing induced drag.
Both cambered and symmetrical airfoils have an angle of attack at which they produce no lift, no induced drag, and no pressure ...

Do symmetrical airfoils generate induced drag?
It depends on the angle of attack. If it is non-zero there will still be a different airflow on both sides - leading to different pressures and thus induced drag.

How high could modern transonic commercial transport designers reasonably push L/D ratios?
First of all, I am sceptical regarding your graph. The Fokker F-28 or the Short 360 are way too good while the Boeing 767 looks poorer than what other sources claim. Size alone helps already by making ...
