Yes. The symbol is Interface_Ethernet:LAN8742A and the footprint Package_DFN_QFN:VQFN-24-1EP_4x4mm_P0.5mm_EP2.5x2.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
QFN-24-EP(4x4), with 25 pins. Its footprint is drawn on this page.
Microchip Technology publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C153279, with 394 in stock; the sellers' links on this page open their listings.
