Overview
The FEAST2.1 is an uncategorised made by CERN in a QFN32 package with 33 pins. Radiation Tolerant 10W Synchronous Step-Down Buck DC/DC converter.
PCBKit's library has its KiCad symbol (Regulators:CERN_FEAST2.1, from CERN's library) and its footprint (ICs And Semiconductors SMD:CERN_FEAST2.1, from CERN's library), ready for a KiCad board.

Questions
Is there a KiCad symbol and footprint for the FEAST2.1?
Yes. The symbol is Regulators:CERN_FEAST2.1 and the footprint ICs And Semiconductors SMD:CERN_FEAST2.1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the FEAST2.1?
QFN32, with 33 pins. Its footprint is drawn on this page.
What can replace the FEAST2.1?
Parts like it in the library: the BPOL12V_V4 by CERN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
