Chris, this a common error made intensionally or not, by many mechanics.
If you take almost any motorcycle, lift it by the middle so that the rear
tire is still on the ground with the front wheel in the air, the front forks
will show some play. If this play was there when the bike is on its wheels,
yes, you replace the fork bushings. But with the forks fully extended, the
leverage and engagement of the tubes is minimal. So it is with the front
struts on your car. Don't believe the specialist for one minute that your
struts are worn out. Probably, your dealer has a way of checking them while
the front wheels are loaded, thus giving you a true picture of the problem.
