How to mount an OLGA package IC for development
Breakout board, custom breakout board, or dead bug.  Not sure if there are any boards available for that particular footprint, but you can always roll a basic breakout board through OSH park.  Rolling you own also gives you an opportunity to get the PCB footprint figured out.  If you don't care to wait for the turnaround, glue the chip to something (perfboard, an unused SMD breakout board of arbitrary footprint with enough pins, etc) and manually make the connections one at a time.
