Why does it operate in a separate process?

Is the reason for using aidl because the process is separated?

Please give more context to your question. It is quite vague what exactly you are asking.

I wonder why 3 services in the ics-openvpn Android app, OpenVPNService, ExternalOpenVPNService, and OpenVPNstatusService, operate on separate processors.
If the reason why it works on a separate processor is to maintain VPN service when there is a problem with the app, is idl a means to use a separate process?

yes, the idea is to keep the backend process as slim as possible that run the VPN itself
