Would I be able to use this software for full body tracking in VR?
would full body tracking be possible with OpenCV in different VR titles, such as VRchat, and other full body compatible titles? If so, how would this work and is there a tutorial in video format?
full body tracking is a difficult quest. You may find some solution in openvino or take a look at openpose.
OpenCV was not made for this. Full body tracking would require a 3D library OR a well combined 2D skeleton based tracking. It is very challenging and not yet solved, so as gino already pointed out, have a look at the OpenVINO available networks for skeleton tracking.
