Questions

Is there a KiCad symbol and footprint for the ATSAMD21J18A-CU?

Yes. The symbol is MCU_Microchip_SAM:ATSAMD21J18A-SAMD21JC and the footprint Package_BGA:UFBGA-64_5x5mm_Layout8x8_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATSAMD21J18A-CU?

UFBGA-64(5x5), with 64 pins. Its footprint is drawn on this page.

Where is the ATSAMD21J18A-CU datasheet?

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

Where can I order the ATSAMD21J18A-CU?

JLCPCB lists it as part C1339746, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ATSAMD21J18A-CU?

Parts like it in the library: the STM32F103R8H7 by STMicroelectronics, the STM32F103RBH6 by STMicroelectronics, the STM32F103R4H6A by STMicroelectronics and the STM32F103R6H6A by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
