Questions

Is there a KiCad symbol and footprint for the EM357-ZRT?

Yes. The symbol is EasyEDA_Cloud:EM357-ZRTR and the footprint EasyEDA_Cloud:VQFN-48_L7.0-W7.0-P0.50-TL-EP5.2, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the EM357-ZRT?

QFN-48(7x7), with 49 pins. Its footprint is drawn on this page.

Where is the EM357-ZRT datasheet?

Silicon Labs publishes it: the Datasheet link on this page opens it.

Where can I order the EM357-ZRT?

JLCPCB lists it as part C5632978, with 0 in stock; the sellers' links on this page open their listings.

What can replace the EM357-ZRT?

Parts like it in the library: the CC1352R1F3RGZ by Texas Instruments, the CC2640R2FTWRGZRQ1 by Texas Instruments, the CC1352P1F3RGZ by Texas Instruments and the CC2630F128RGZ by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
