Actually there is an internet permission.
To perform network operations in your application, your manifest must include the following permissions:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Though you can get away with firewall-ing any app you don't want connecting to the internet using apps such as netguard or afwall+.
Open source keyboards you've mentioned are probably your best bet if privacy is your main concern.
