If my opponent used Turtonator's "Shell Trap" attack and I have Espeon VMAX with the "Solar Revelation" Ability in play, will my Attacking Pokemon with energy attached receive the 8 damage counters from "Shell Trap" if I attack and do damage to Turtonator?
No, it will not receive the 8 damage counters. Solar Revelation prevents all effects of your opponent's attacks, and Shell Trap's damage counters are an effect of your opponent's attack.

Does Espeon's "Solar Revelation" Ability prevent damage done to Benched Pokemon?
No, it does not. Unlike placing damage counters, doing damage to a Benched Pokemon is not prevented by Solar Revelation.

Does Espeon's "Solar Revelation" Ability prevent moving or placing damage counters?
In the steps of resolving an Attack, moving or "placing Damage Counters" counts as an Effect of the attack; it is not part of "doing damage". Therefore, as an Effect it would be prevented by Solar Revelation.

Does Espeon's "Solar Revelation" Ability prevent the flipping of coins for an attack that does damage times the number of heads flipped?
No, it does not. Flipping coins in this context is used to calculate how much damage is to be done. Since "doing damage" is not prevented, the flipping is not prevented either.
