Questions

Is there a KiCad symbol and footprint for the STM32L433RBY6?

Yes. The symbol is MCU_ST_STM32L4:STM32L433RBYx and the footprint Package_CSP:ST_WLCSP-64_Die435, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STM32L433RBY6?

WLCSP-64(3.1x3.1), with 64 pins. Its footprint is drawn on this page.

Where is the STM32L433RBY6 datasheet?

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

Where can I order the STM32L433RBY6?

JLCPCB lists it as part C2054356, with 0 in stock; the sellers' links on this page open their listings.

What can replace the STM32L433RBY6?

Parts like it in the library: the STM32L431RBY6 by STMicroelectronics, the STM32L431RCY6 by STMicroelectronics and the STM32L433RCY3 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
