I ran out of GPIO on my RPI and now looking for a module to converts USB to GPIO for my Raspberry. I am not interested in converting GPIO to USB, but interested in USB to GPIO. I've been googling for some time but haven't found anything like this. Do you maybe know if a product like this exists, that I can connect to my raspberry, and use some extra, additional GPIO ports?

You can connect a Pi Zero via USB to your current Pi. That will give you 26 additional GPIO.
You are extremely unlikely to find any such device.
Most of us would use a GPIO extender. There are several that work over I²C.
