Is there a KiCad symbol and footprint for the LM43603PWPR?

Yes. The symbol is EasyEDA_Cloud:LM46000QPWPTQ1 and the footprint EasyEDA_Cloud:TSSOP-16_L5.0-W4.4-P0.65-LS6.4-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM43603PWPR?

TSSOP-16-EP, with 17 pins. Its footprint is drawn on this page.

Where is the LM43603PWPR datasheet?

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

Where can I order the LM43603PWPR?

JLCPCB lists it as part C412826, with 5,695 in stock; the sellers' links on this page open their listings.

What can replace the LM43603PWPR?

Parts like it in the library: the LTC3412AEFE#TRPBF by Analog Devices, the LTC3413IFE#PBF by Analog Devices, the ADP2380AREZ by Analog Devices and the LT1765EFE-1.8#PBF by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
