Is there a KiCad symbol and footprint for the STM32L432KCU6?

Yes. The symbol is MCU_ST_STM32L4:STM32L432KCUx and the footprint Package_DFN_QFN:QFN-32-1EP_5x5mm_P0.5mm_EP3.45x3.45mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STM32L432KCU6?

UFQFPN-32(5x5), with 33 pins. Its footprint is drawn on this page.

Where is the STM32L432KCU6 datasheet?

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

Where can I order the STM32L432KCU6?

JLCPCB lists it as part C1337280, with 43 in stock; the sellers' links on this page open their listings.

What can replace the STM32L432KCU6?

Parts like it in the library: the STM32L431KCU6 by STMicroelectronics, the STM32L412KBU6 by STMicroelectronics, the STM32H503KBU6 by STMicroelectronics and the STM32L432KBU6 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
