A number of these interfaces are addressed in the existing post Surprisingly many network interfaces on macOS: are these legitimate?

As this is a mobile device , there are some additional interfaces:

• ap1 is an Access Point interface. This is if you turn it into a hotspot
• llw0 is Low Latency WAN link. It is part of the (highly undocumented) SkyWalk subsystem
• ipsecX are VPN links. While you aren’t using VPN currently, iOS is capable of VPN connectivity and these would be the interfaces used
• pdp_ipX are cellular network interfaces like 5G, LTE, etc.
• XHC0 is a USB interface likely for tethering
