have you driven either of these cars? impossible to slide out ? yeah right, no lsd makes a car impossible to slide out, actually lsds make a car easier to slide out, if you had a car with open diffs then throttle will just make the inside tyre spin which has minimal grip and has least effect on the cornering attitude of the car, lsds make it turn tighter by sending the torque to the outside wheel, this if anything makes the car EASIER to spin out, perhaps you're thinking of stability and traction control, both of which arnt used in racing, well most of them anyways
