When we talk about safety tools in a ttrpg settinv, we're usually discussing tools to reduce bleed and strengthen alibi (distancing yourself from your character prevent out of character fights, played trauma, etc). I don't know if those tools would translate well to a game that has no characters, and therefore bleed.
I am however in favor of any tool that helps create an environment where players can enjoy playing, so safety tools for non-ttrpg games may look more like accessibility tools.
