The California city is seeking to host the summer Games for a third time in a bid that centred on celebrating diversity.
The call took place on Wednesday and was arranged by Los Angeles Mayor Eric Garcetti, who had previously said Trump's win after a campaign filled with harsh rhetoric toward immigrants, Hispanics, Muslims and women could be detrimental given the international makeup of the IOC's voting members.
The IOC, which will also consider bids from Paris and Budapest, will select the host next September.
