The tough love approach is not giving in to their begging and feeding them more pellets, but leaving the lettuce in there as their main food source. They will come around and eat it if there's not much else to eat.
You might try some aquatic plants. I feed my turtle Anarchis and Hornwort. While he's picky about some vegetables, he dug right into those the minute I first put them in the tank.
Also, it's fairly common for the turtle to spit back out some of the lettuce. They just tear off a bigger bite than they're able to chew at once, and spit the excess back out to eat later.
