Is there a KiCad symbol and footprint for the AC6956A4?

Yes. The symbol is EasyEDA_Cloud:AC6956A4 and the footprint EasyEDA_Cloud:QFN-32_L4.0-W4.0-P0.40-BL-EP2.7-A, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AC6956A4?

QFN-32, with 33 pins. Its footprint is drawn on this page.

Where is the AC6956A4 datasheet?

JieLi Tech publishes it: the Datasheet link on this page opens it.

Where can I order the AC6956A4?

JLCPCB lists it as part C5440138, with 11 in stock; the sellers' links on this page open their listings.

What can replace the AC6956A4?

Parts like it in the library: the HT32F50241-33QFN by Holtek Semicon, the HC32F420FAUB-QFN32TR by XHSC and the STC32G8K64-42I-QFN32 by STC Micro. Check their datasheets: a part that fits the footprint may still differ in its ratings.
