How long does it take by a private Driver to get from MXP airport in Milan to Bellagio? Thank you!

That will give you a good estimate.
Estimates I've seen generally average around 1 hour, 30 minutes to 2 hours, depending on traffic.
We used Bellagio Taxi and I think it was about 2 hours each way. Always seemed to run into road work, but the driver did manage to avoid high traffic areas.
