Questions

Is there a KiCad symbol and footprint for the SC91F744P44R?

Yes. The symbol is EasyEDA_Cloud:SC91F744P44R and the footprint Package_QFP:LQFP-44_10x10mm_P0.8mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SC91F744P44R?

LQFP-44(10x10), with 44 pins. Its footprint is drawn on this page.

Where is the SC91F744P44R datasheet?

SOC publishes it: the Datasheet link on this page opens it.

Where can I order the SC91F744P44R?

JLCPCB lists it as part C221372, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SC91F744P44R?

Parts like it in the library: the ATMEGA32A-AU by Microchip Technology, the STC89C52RC-40I by STC, the STM8S105S4T6C by STMicroelectronics and the PIC16F1939-I/PT by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
