Is there a KiCad symbol and footprint for the LM2756TMX?

Yes. The symbol is EasyEDA_Cloud:LM2756TMX_NOPB and the footprint EasyEDA_Cloud:DSBGA-20_L2.0-W1.6-R4-C5-P0.40-BL-1, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM2756TMX?

DSBGA-20, with 20 pins. Its footprint is drawn on this page.

Where is the LM2756TMX datasheet?

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

Where can I order the LM2756TMX?

JLCPCB lists it as part C2679378, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM2756TMX?

Parts like it in the library: the LM2756TM by Texas Instruments, the LM3633YFQR by Texas Instruments, the LM3646YFQR by Texas Instruments and the LP8556TME-E05 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
