Have endgame tablebases ever been compiled for smaller variants of chess? I am interested in compiling endgame tablebases for a few miniature chess variants, such as Chess Attack (5x6) and Los Alamos Chess (6x6). Have these ever been created before, and if so, are they publicly accessible?

Perhaps you should ask contact these people since they have solved Gardner and Mallet Chess and are trying to solve Los Alamos Chess which Prost believed to be a draw.
