Questions

Is there a KiCad symbol and footprint for the STM32L021D4P6?

Yes. The symbol is MCU_ST_STM32L0:STM32L021D4Px and the footprint Package_SO:TSSOP-14_4.4x5mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STM32L021D4P6?

TSSOP-14, with 14 pins. Its footprint is drawn on this page.

Where is the STM32L021D4P6 datasheet?

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

Where can I order the STM32L021D4P6?

JLCPCB lists it as part C192083, with 0 in stock; the sellers' links on this page open their listings.

What can replace the STM32L021D4P6?

Parts like it in the library: the PIC16LF1455-E/ST by Microchip Technology, the PIC16LF1455-I/ST by Microchip Technology, the PIC16LF1613-E/ST by Microchip Technology and the PIC16LF1613-I/ST by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
