Questions

Is there a KiCad symbol and footprint for the ATMEGA329A-MU?

Yes. The symbol is EasyEDA_Cloud:ATMEGA169-16MU and the footprint EasyEDA_Cloud:QFN-64_L9.0-W9.0-P0.50-BL-EP5.4, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATMEGA329A-MU?

QFN-64-EP(9x9), with 65 pins. Its footprint is drawn on this page.

Where is the ATMEGA329A-MU datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the ATMEGA329A-MU?

JLCPCB lists it as part C1339068, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ATMEGA329A-MU?

Parts like it in the library: the PIC24FJ256GL406-I/MR by Microchip Technology, the PIC24FJ512GL406T-I/MR by Microchip Technology, the PIC16F19196-I/MR by Microchip Technology and the PIC16LF1526-I/MR by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
