Olson moved into the mainstream with her role as Joanna Anderson in the 2003 holiday film Love Actually, singing the song "All I Want for Christmas Is You".{{cite web|last=Hough|first=Q.V.|url=https://screenrant.com/love-actually-cast-guide-actors-movies-cameos/|title=Love Actually Cast Guide: Every Actor & Cameo|website=Screen Rant|date=July 5, 2021|archive-url=https://web.archive.org/web/20210723031733/https://screenrant.com/love-actually-cast-guide-actors-movies-cameos/|archive-date=July 23, 2021|url-status=live}}{{cite web|last=Fletcher|first=Henry|url=https://www.digitalspy.com/movies/a778188/heres-what-the-love-actually-kids-joanna-and-sam-olivia-olson-and-thomas-brodie-sangster-look-like-now/|title=Here's what the Love Actually kids Joanna and Sam look like now|website=Digital Spy|date=December 24, 2015|access-date=July 22, 2021|archive-url=https://web.archive.org/web/20200803172304/https://www.digitalspy.com/movies/a778188/heres-what-the-love-actually-kids-joanna-and-sam-olivia-olson-and-thomas-brodie-sangster-look-like-now/|archive-date=August 3, 2020|url-status=live}} Her singing was praised, with director Richard Curtis stating in the commentary in the music section of the Love Actually DVD that Olson's singing was so perfect, they were afraid the audience would not believe that a ten-year-old could really sing the way she did and would assume she was lip-synching. They had to train her so her singing would sound more believable, and add the sounds of inhalations to the track. This led to guest spots on The Ellen Show, The Tracy Morgan Show and singing with stars Jack Black and Kristin Chenoweth. Olson also posted original songs on her YouTube account. In 2017, Olson reprised her role as Joanna in Red Nose Day Actually, a short film which is a sequel to Love Actually.

From 2008 to 2015, Olson voiced the recurring character Vanessa Doofenshmirtz in the Disney animated series Phineas and Ferb along with actor Thomas Sangster (Ferb Fletcher), who played Joanna's love interest Sam in Love Actually.{{cite web|last=O'Brien|first=Conor|url=https://screenrant.com/phineas-ferb-facts-trivia/|title=10 Things You Didn't Know About Phineas and Ferb|website=CBR|date=April 2, 2020|archive-url=https://web.archive.org/web/20210227000713/https://screenrant.com/phineas-ferb-facts-trivia/|archive-date=February 27, 2021|url-status=live}}{{cite web|last1=McMillian|first1=Laurise|last2=Chilton|first2=Charlotte|url=https://www.elle.com/culture/movies-tv/news/g29142/your-favorite-christmas-movie-stars-now/|title=What Your Favorite Christmas Movie Stars Look Like Now|website=Elle|date=November 20, 2019|access-date=July 22, 2021|archive-url=https://web.archive.org/web/20210101074326/https://www.elle.com/culture/movies-tv/news/g29142/your-favorite-christmas-movie-stars-now/|archive-date=January 1, 2021|url-status=live}}{{cite web|last=Rosa|first=Christopher|url=https://www.vh1.com/news/cxbji2/llove-actually-little-girl-grown-up|title= The Little Girl From Love Actually Is Gorgeous Now—And Still Singing|website=VH1|date=December 2, 2015|access-date=July 22, 2021|archive-url=https://web.archive.org/web/20160213052835/http://www.vh1.com/news/227670/llove-actually-little-girl-grown-up/|archive-date=February 13, 2016|url-status=live}} Olson said that she and Sangster talked "about the whole Ferb-Vanessa situation 'cause it's pretty funny."{{cite magazine|last=Bierly|first=Mandi|url=https://ew.com/article/2009/12/17/love-actually-olivia-olson/|title=All 'Love Actually' scene-stealer Olivia Olson wants for graduation is a record deal|magazine=EW|date=December 17, 2009|archive-url=https://web.archive.org/web/20210429185648/https://ew.com/article/2009/12/17/love-actually-olivia-olson/|archive-date=April 29, 2021|url-status=live}}
