I use perfect privacy and they provide IPSec configs for iOS. Their guide even makes note to enable on-demand to prevent leaks. Also, just checked Mullvad, which seems to open an IPSec server on your local device and then install a vpn config on your ios device. From the local IPSec server a connection is made to mullvad via wireguard. On-demand is also enabled by default. But yea, VPN were initially targeted at enterprises anyway. So I don’t mind that i actually have to install vpn profiles by hand.
