Update, based on this thread I've tried to install the following:
opkg update
opkg install python3 python3-pip
opkg install luci-ssl-openssl curl ca-bundle #error - opkg_install_cmd: Cannot install package luci-ssl-openssl.
pip install virtualenv
opkg install python3-dev
opkg install gcc
pip install --upgrade pip
But I'm still unable to install RPi.GPIO using pip or pip3
