not sure if you have any feedback at the end but if you do the alternative is feedback poisoning in your training set to mark AI stuff as real and real stuff as fake. The former is automatable and if there were a good reason you could probably mechanical-Turk a large number of people at low cost to do it for real and give feedback that they were actually AIs.

An AI-proof writing tool is a pen and paper, on a glass table, in a Faraday-cage locked room, etc, etc.

Depending on how high are the stakes, weeding off just the most obvious cases of AI usage may be enough. But wherever an electronic input is involved, it can be emulated in ways that are impossible to detect on a reasonable budget. Content analysis may help somehow, but again it would only detect the more obvious cases.

Or write a script that does all that and bind it to shortcut. Eventually https://files.catbox.moe/zargud.png. (The window/tab switches were 1~2 when ended; reached 9 after few attempts to screenshot it.)
