Yes they will be open.
I'm sure that someone who does live locally will have answers because I live in La Grande, Oregon but when I visit other cities that have Olive Garden restaurants, my husband and I always make a point to eat at Olive Garden.
On Tuesday December 24 is 11am to 8pm , on December 25 is Wednesday it is holiday and on December 26 Thursday 11am to 10 pm Kindly call them once before you plan to check the availability and reservation to avoid busy hours waiting. Hope you enjoy your visit.
