Any old CV based Titan2 script should do. From what I understand, the alternative to Titan as hardware + capture card would be remoteplay, but apparently it's disabled on Valorant (? someone may need to fact check this)\
Aimengine/Helios are some options, though you should be careful since heuristic based detection of CV cheats (based on how joystick inputs are sent/natural aim patterns) is not exceedingly difficult and it's more than likely that a detection wave is somewhere on the horizon.
