Is there a KiCad symbol and footprint for the FT231XQ-R?
Yes. The symbol is Interface_USB:FT231XQ and the footprint Package_DFN_QFN:QFN-20-1EP_4x4mm_P0.5mm_EP2.5x2.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
Where is the FT231XQ-R datasheet?
FTDI Chip publishes it: the Datasheet link on this page opens it.
What can replace the FT231XQ-R?
Parts like it in the library: the SE5004L by Skyworks Solutions, the NRF24L01P-R7 by Nordic Semiconductor and the NRF24L01P-T by Nordic Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
