Questions

Is there a KiCad symbol and footprint for the LM2757TM?

Yes. The symbol is EasyEDA_Cloud:LM2757TM_NOPB and the footprint EasyEDA_Cloud:DSBGA-12_L1.6-W1.2-R3-C4-P0.40-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM2757TM?

DSBGA-12(1.2x1.6), with 12 pins. Its footprint is drawn on this page.

Where is the LM2757TM datasheet?

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

Where can I order the LM2757TM?

JLCPCB lists it as part C2073324, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM2757TM?

Parts like it in the library: the LM2757TMX by Texas Instruments, the TPS63050YFFT by Texas Instruments and the TPS63051YFFT by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
