Lolsrslybro GmsCompatConfig is part of GrapheneOS, it's not a Google app.
It only comes into play when you install play services and is part of the compatibility layer.
In reality, all it is is a text file with configuration options for the compatibility layer so updates to it can be shipped via Apps instead of requiring an OS update.
It's 100% harmless, leave it as it is and update it as updates come :)
