Uh...First of all: Good olimar mains dont get gimped that often. Maybe in some of the wifi sites that you play on or maybe even on AiB but still they rarely get gimped.
Second: As far as killing goes, Olimar has a MUCH easier time killing than we do. Killing for toonlink is a big problem and most toonlink already know that.
And Thirdly: Yes i will agree with you, toonlinks projectiles are amazing but they aren't a game changing factor in this match up especially since olimar can out camp toonlink.
Also...purple are annoying as ****. I have learned to powershield them since i play against Finos olimar pretty much everyday offline.
Here is an old tourney vid of how annoying purples used to be and how much of a nuisance they really can be to any character.

Not to sound like i am attacking you but if you actually play a good olimar, your eyes will be opened to a WHOLE-nother perspective.
Im sure one of these olimars are willing to play you.
