According to the docs:
Unlike the native Android API, if autoConnect=true while using this library there will be NO attempts to automatically reconnect if the original connection is lost.
I'd like the phone/app to be connected when back in range even if the app is not being used when it happens, I don't really care about the app, just need the phone to be connected.
If I'm not mistaken, the native API would trigger a reconnection even if the app is not running as long as the devices are paired/bonded (is that assumption correct?).
How could I achieve this using RxAndroidBle? Is running a foreground service with an annoying sticky notification the only way?

This assumption is not correct. You would still need the process which started the connection to be around.

You have answered your question — the same statement is true when using the native API (which used by RxAndroidBle under the hood actually)
