There’s no way to mitigate the risk of statistically random meteorites that can come from any direction.

The primary mitigation is to use predictions of larger events, such as meteor showers, and move the observatory to an orientation that reduces the risk of damage.

Sure there is! Put a shroud around it in every direction but the light-collection direction. That'd mitigate like 90% of the meteors.
