What's creating rattle sound from front drivers side whenever I go over bumps?

We replace the top mounting plates of the struts on most Toyota/Lexus products because of the noise. The bearing inside that lets you turn the wheel freely has worn out. If you still hear noises from the drivers side then something else like a sway bar end link or the strut itself could be loose or damaged. Have someone bounce the vehicle if they can while you listen for the noise. Sometimes you get lucky and find it. It not then take it back to the original shop and explain that the noise is still there and to find it. Be persistent, you're the customer! Good luck.
