Some of the text displayed in game isn't read from data/text folders, it's from:
DRIVE:\Steam\steamapps\common\Total War ROME REMASTERED\Contents\Resources\en.lproj\Localizable_Game.strings
these strings can be changed and included in modfolder just duplicate the file and place it in the following location:
mod-folder\data\string_overrides\en.strings
This example is for english same principle applies on other languages. Instructions are contained in the readme.txt inside data/string_overrides: This folder is used to override strings added to the game by Feral Interactive.
NOTE: The original override files can be found at ".lproj/Localizable_Game.strings" Override files should be named the language code they correspond with and have the file extension, ".strings" E.G. English Override: "en.strings"
