Almost. Luckily, I still had Ragehook 52 in my DL folder, which only supports patch 1032. Ragehook 53 only supports 1033. So I removed RH, reinstalled 52, declined the update. I also declined to uninstall OpenIV. Also, luckily, I have 3 backups of my GTA V folder, so I replaced my default folder's GTA5.exe, GTA5Launcher.exe, and installScript.vdf with the ones from one of my backups. Then, I disabled auto update in Steam. Now, for me at least, RH wouldn't launch the game, it threw an error saying the game wasn't launched via Steam. So I learned that if I launch it from Steam, then run RageHook, it works. I am now happily patrolling Los Santos again!
