LUKS doesn’t protect you from an evil maid attack. It hides your data when your stuff gets stolen in a powered off state, but it provides neither verification of data, nor does it provide verified/secure/safe boot.
In simple terms: the very first thing which gets loaded needs to be unencrypted (barring some exceptions I will omit here), which can get replaced with an evil version by the evil maid.

Saying the source is available to see, that makes sense though.
I don’t think that’s the correct path. There is a scanner already, called ClamAV, which works well enough.
Virus scanners don’t fix the problem though. Android does it better: security by isolation and verification of system components.

It’s quite a political thing, but I am sure you’ll find your way around it.
