Questions

Is there a KiCad symbol and footprint for the MSA321?

Yes. the footprint 4ms_Package_QFP:LGA-12_2x2mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MSA321?

LGA-12(2x2), with 12 pins. Its footprint is drawn on this page.

Where can I order the MSA321?

JLCPCB lists it as part C51928205, with 3,841 in stock; the sellers' links on this page open their listings.

What can replace the MSA321?

Parts like it in the library: the LIS2DW12 by STMicroelectronics, the SC7A20HTR by Hangzhou Silan Microelectronics, the LSM303AGR by STMicroelectronics and the QMA6100P by QST. Check their datasheets: a part that fits the footprint may still differ in its ratings.
