Is there a KiCad symbol and footprint for the LP6255QVF?

Yes. The symbol is EasyEDA_Cloud:LP6255QVF and the footprint EasyEDA_Cloud:QFN-20_L3.0-W3.0-P0.40-BL-EP1.7, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LP6255QVF?

QFN-20-EP(3x3), with 21 pins. Its footprint is drawn on this page.

Where is the LP6255QVF datasheet?

LOWPOWER publishes it: the Datasheet link on this page opens it.

Where can I order the LP6255QVF?

JLCPCB lists it as part C517065, with 6,056 in stock; the sellers' links on this page open their listings.

What can replace the LP6255QVF?

Parts like it in the library: the LGS51215 by Legend-Si, the TPS51225CRUKR by Texas Instruments, the TMI7003 by TMI and the TMI7003B by TMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
