Questions

Is there a KiCad symbol and footprint for the SY58040UM?

Yes. The symbol is Analog & Interface:SY58040U and the footprint ICs And Semiconductors SMD:QFN50P700X700X100-45N-S340, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SY58040UM?

QFN44, with 45 pins. Its footprint is drawn on this page.

What can replace the SY58040UM?

Parts like it in the library: the SY58038UMY by MICREL, the SY89113UMY by MICREL and the SY89859UMY by MICREL. Check their datasheets: a part that fits the footprint may still differ in its ratings.
