Questions

Is there a KiCad symbol and footprint for the LM4844TL?

Yes. The symbol is EasyEDA_Cloud:LM4844TL_NOPB-NS and the footprint EasyEDA_Cloud:DSBGA-30_L3.0-W2.6-R5-C6-P0.50-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM4844TL?

DSBGA-30, with 30 pins. Its footprint is drawn on this page.

Where is the LM4844TL datasheet?

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

Where can I order the LM4844TL?

JLCPCB lists it as part C4991042, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM4844TL?

Parts like it in the library: the LM4844TL/NOPB-NS by Texas Instruments, the LM4857ITL by Texas Instruments and the LM48903TLX by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
