Is there a KiCad symbol and footprint for the MP7748SGF-Z?

Yes. The symbol is EasyEDA_Cloud:MP7748DF-LF-P and the footprint EasyEDA_Cloud:TSSOP-28_L9.7-W4.4-P0.65-LS6.4-BL-EP5.5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MP7748SGF-Z?

TSSOP-28-EP, with 29 pins. Its footprint is drawn on this page.

Where is the MP7748SGF-Z datasheet?

Monolithic Power Systems publishes it: the Datasheet link on this page opens it.

Where can I order the MP7748SGF-Z?

JLCPCB lists it as part C6993369, with 22 in stock; the sellers' links on this page open their listings.

What can replace the MP7748SGF-Z?

Parts like it in the library: the MAX9750CEUI by Maxim Integrated (Analog Devices), the IS31AP2112-ZLS2-TR by ISSI, the MAX9760EUI by Maxim Integrated (Analog Devices) and the MAX9761EUI by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
