>I wouldn't say these anti-cheat tools that come with Valorant or LoL are from dubious origins.
You are talking about Vanguard, developed by Riot which is owned by Tencent which is a Chinese company? China has demonstrated enough grip on companies over the years that anything China can directly influence is dubious. China can decide to do something with the installations and has the power to do it in secret. It is significantly harder in western democracies. The relationship between the state and the private enterprises is entirely different.
Valve's VAC is not in the same league with Vanguard from a technical point of view (it is not even kernel based if I'm not mistaken). I would not let that slide either if it was though.
At least in terms of video games investment, Tencent is known to be very hands-off of the western companies it owns and is often seen to be a better option vs some western conglomerates. Ubisoft turning to Tencent to help it fight off a takeover attempt from Vivendi is a pretty good example.
Vanguard itself is developed by a US-based team and they've stated that they have very little to do with Tencent's anti-cheat team (Tencent uses its own solution for the CN region, including for Riots game) beyond sharing cheat samples.
