Honest question about Kalista

The vast majority of her mechanics involve mashing the attack move button.

Attack move prioritizes a target within the champions attack range as they move toward the cursor, prioritizing champions over minions (I think, something changed about that recently to make it easier) but still targetting the closest target to the cursor. On ranged champions, because their attack range is large, you can actually alternate between walking and attack moving backwards (aka the cursor isn't near the enemy champion but is instead always behind your champion) to kite much easier than using the mouse.

Kalista is special because of her passive, which allows for movement in between auto attacks and also makes it so that auto attacks can't be cancelled. What this means is that she can spam her attack move button behind her and she will auto the closest target and in between will jump backwards. All you have to do is mash the attack move button.

By removing all skill involved by building hurricane, shift clicking the ground, and hitting E once in a while. Congrats, now you can pretend you're good at ADC by playing a mistake champion who plays the game for you.
