The former winger was promoted to president of business operations on Friday by Kings governor Tim Leiweke.
Robitaille was drafted 191st overall by Los Angeles in 1984, played for the Kings three separate times during his career and retired from the organization after the 2005-06 season.
He worked this past year as an assistant to Leiweke, who is also CEO of the Kings parent company Anschutz Entertainment Group.
"I have invested so much of myself into this organization since I was drafted here in 1984 and I look forward to the opportunity to truly have an impact on our future success," said Robitaille. "I have gained tremendous experience this past year with AEG and the Kings and I look forward to continued growth as a business professional in this great city.
"The opportunity to have a significant impact on how our fans experience this team and our players is something I am extremely excited about."
In his new role, Robitaille will oversee the day-to-day business operations of the Kings. His time will focus directly on all business initiatives as it relates to the team.
Robitaille will also work closely with Kings president and GM Dean Lombardi.
"This is a critical step for AEG to give the Kings stand-alone leadership and staffing that does nothing but focus on the Kings," said Liewicke. "We want the Kings to have independent leadership and a specific focus while maintaining the ability to utilize the vast resources of AEG.
"Putting Luc in this position alongside our leader on the hockey side, Dean Lombardi, gives us a tremendously passionate leadership team with a desire to win that will be second to none."
Robitaille, who had his No. 20 jersey retired by the Kings in January, is the team's all-time leader in goals (557).
He had 1,394 career points (668-726) in 1,431 regular-season games with Los Angeles, Detroit, Pittsburgh and the New York Rangers. Robitaille also ranks second all-time in Kings history in games played (1,077), second in points (1,154) and fourth in assists (597).
