No, you don't.

On other platforms, firewall software is needed to protect open communication ports against intrusion. Because iOS achieves a reduced attack surface by limiting listening ports and removing unnecessary network utilities such as telnet, shells, or a web server, no additional firewall software is needed on iOS devices.

Where are you seeing this? I looked on my 6th Gen iPad, and brand new iPhone SE, both running iOS 15.5. Neither has any such option.

The only way I could assume you're seeing such a message is you, or someone who also uses your iPhone installed a third party firewall app and it's currently turned off. Garbage apps such as Kaspersky Security & VPN, McAfee Security: VPN and others have them.
