If your phone is rooted you can use any standalone keyboard app you like as long as you block it's internet access
Not rooted for once in a long time, but I'll think about it. How do you restrict an app's access?
If you do not have an LSposed framework or similar (formerly knows as Xposed Framework) you can either use Adaway for blocking the phone from reaching websites (keep in mind that this is globally, though) or e.g. AFWall+ for preventing single Apps to connect to the internet (Apps that don't try to get internet access are not shown is the list provided by AFWall+).
If you have LSposed or similar I believe it is possible to install XprivacyLua. This was/is(?) a very powerful tool to manage every single access an app is trying to get. Why would a sketchy chinese calculator app need access to the contacts and the internet even though this was never allowed in the system settings?
OP can't use adaway or AFWall+ without root.
I'm in the same boat as OP (I have a device without root for the first time in a long time) and I miss both apps. I do use a pihole+VPN for what adaway does. But there's no real replacement for AFWall/iptables without root. As pointed out, though, you can block individual apps in some modern versions of android. Fortunately, I have that.
Yes but they asked anyway, so I posted a few options
