Di Lorenzo was born in Pittsburgh, Pennsylvania but raised in Columbus, Ohio, after her family moved there when she was around the age of seven. Her parents, Carlo and Daniela Di Lorenzo, are Italian immigrants from Salerno.  Carlo is a physician at Nationwide Children's Hospital in Columbus and Daniela teaches Italian at various colleges. Di Lorenzo attended New Albany High School in New Albany, Ohio.
She has three siblings, and Cristina, her oldest sister, also played tennis at the collegiate level at Xavier University and graduated in 2017. Mario, her oldest brother, also has an athletic background as he won an intramural championship in the inaugural season of wheelchair basketball at The Ohio State University.
Di Lorenzo is fluent in Italian. As a child, she played both tennis and soccer.
Coming out of high school, Di Lorenzo was ranked as the nation's top tennis recruit. She committed to playing collegiate tennis at The Ohio State University. In her final tournament as a junior, she reached the semifinals in both the girls' singles and doubles tournaments at the 2015 US Open.
As a freshman, Di Lorenzo began her season by winning the USTA/ITA National Indoor Intercollegiate Championship, claiming the Buckeyes' first national title in its program's history. She defeated Joana Eidukonyt? in the championship match, and concluded the season with a 37-5 record, setting the program record for most victories in a season, and was named singles all-American.
During her sophomore year with the Buckeyes, Di Lorenzo went 37-2 in singles, equaling her school record from the previous year. She also finished the year as the top-ranked women's NCAA singles player. Di Lorenzo repeated as the USTA/ITA National Indoor Champion, beating Hayley Carter in the final. She capped off her sophomore season by winning the NCAA Women's Doubles Championship with her partner, Miho Kowase. This championship was the program's first NCAA in its history. For her accomplishments during the season, Di Lorenzo was named both singles and doubles all-American.
Di Lorenzo earned a wild card into the qualifiers of the singles tournament at the 2017 US Open. There she also received a wild card for the main draw of the doubles tournament and made her Grand Slam debut, partnering with Allie Kiick.
On December 18, 2017, Di Lorenzo announced that she would be leaving Ohio State to become a professional tennis player.
