What USB-C Footprint is this?
welcome at EE.SE
An example for such a connector can be found here: https://www.digikey.com/en/products/detail/assmann-wsw-components/AUSB1-DFN-PTR3/5810164
The footprint is just a practical combination of smd and tht to use the board-space in a more efficient way.
I wish you luck with whatever you want to achieve with this board :)
