Yeah, the barbies were arranged like the guys in video, but you know what? There are a million gang-bang pornos that have a bunch of naked men standing around a naked girl, too (or so I hear).
Which begs the question of where his child would have come across something like that.
Also, Marty learns in 1995 that LeDoux et. al. are doing terrible things to children. That's the same time frame in which the daughter draws explicit sexual drawings and arranges her dolls in a sexually explicit way.
If you want to say that Marty's failure to connect the dots is due to his inattention, that's fine, but the dots are there for him to connect.
