From NordVPN Re Tunnelvision We would like to reassure you that none of our applications leak traffic if 'Stay invisible on a local network' (from iOS 16) and 'Kill Switch' features are enabled within the app settings menu. Side channel attack would result in lost Internet connection, but not the data leak as well. In theory, the attacker could exploit the vulnerability if: they have access to the network their target is connected to; they know the destination IP the target is trying to access; resources target is trying to access are not under any kind of CDN. If all of these requirements are met, attacker could try to block certain IP addresses and then guess whether the target's traffic has dropped because of it. This could reinforce their beliefs that the target is visiting the website they are suspecting, but it would still be probabilistic. That said, even in this case, it won't provide attackers with any content of the target's requests.
