Atleast 70% of the AD Marksman require very little to no aiming. Just a bunch of auto attacking.
I want to play Jhin but I do not have the IP to afford him. His gameplay makes him look like the most marksman out of any ADC
Ez has to hit his Q consistently. Varus as well.
even the easiest adcs require you to be able to dodge abilities and have fast reflexes.
Theyre not "marksmen". Thats just a stupid name Riot threw on there to try to make their game sound more like WoW.
If you want an ADC that uses skillshots 
is pretty much THE skillshot guy.
Its also called a tank except... they dont have https://i.gyazo.com/d33c260a1178ea243cb9157c76e4acdc.png kappa
all require skill shots. The only adcs that dont are vayne and Twitch.
I get what you mean though. Theyre aa based but thats what makes them ADCs. Otherwise theyd have to rework all ADCs which would be sort of pain on riot at this point tbh
Are you asking for a full skill shot champion where his basic attacks are skill shot too ?
Ezreal and Varus are also heavy on skill shots.
Ah, but it's like my boy 
always says:
"Shooting's easy, aiming's the hard part"
.... They are called Marksman because they attack from range :I and most of their damage comes from auto attacks.
Skillshots are not guaranteed.
I mean the definition of Marksman is simply "a person skilled in shooting". I doesn't have to do with skillshots.
They should rework varus to allow him to play like his old version when he was played full lethality... and give him a Darkin trait.
it harder to right click something with a small hitbox in the middle of a moving targets than it is to land a skillshot... at least in my opinion...
i cant adc to save my life... but i and land nidalee spears unconsciously
jhin is so fun
Varus plays the role of sniper quite well too. Those blind max range Q's to secure a long distance kill are so nice. Also the cast time is long so the enemy goes into the "here comes the Q, gotta dodge it!" mode so you're playing a small mini game. It's very rewarding being able to consistently land those snipes.
say hi
has only skillshots in his kit. I don't remember his cost but if you look for something that can kill with an aimed ability that's him.
