TBH, I am not sure how the S1GW should behave in this case. […]
From my understanding in 3GPP TS 36.413, "INITIAL CONTEXT SETUP FAILURE" means the eRABs were never created because the request failed, hence they should all be considered as not created. So yes, upon receiving that we should tear down related UPF sessions.
