That's the problem bro. Its not a Google Play problem in case of Fifa 14.
Android 14 introduced a change which blocks installation of apps which target Android 6 and below. No matter which OEM you use, this is across the board.
Target means that the app is built according to whatever features are available on that particular android version.
The app may continue to work on a higher version of android, but that is not guaranteed (Eg. Like current Android 14).
Your Fifa 14 game targets Android 2.3.3. It would have kept working all the way till Android 13, but this was also never guaranteed.
With this breaking Android 14 change, you won't be able to install Fifa 14. There are no workarounds to this.
On the contrary, if a developer targets the latest Android version, they have to support the app from that version all the way down till the minimum Android version they've defined in their build.gradle files. This is the primary reason why app developers prefer releasing updates first on iOS instead of Android. Because they know that everyone will be on the latest iOS version on Day 1 itself. Worst case they will have to support latest minus 1 iOS version for iPhones incompatible with the latest iOS releases.
