Questions

Is there a KiCad symbol and footprint for the LM4922TL?

Yes. The symbol is EasyEDA_Cloud:LM4922TLX_NOPB and the footprint EasyEDA_Cloud:BGA-14_L2.0-W2.0-P0.50-BL_TI_LM4926TL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM4922TL?

DSBGA-14, with 14 pins. Its footprint is drawn on this page.

Where is the LM4922TL datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM4922TL?

JLCPCB lists it as part C4991088, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM4922TL?

Parts like it in the library: the LM4920TL by Texas Instruments, the LM4922TLX by Texas Instruments, the LM4926TL by Texas Instruments and the LM4926TLX/NOPB-NS by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
