I have never met an Orthodox teacher or clergy who have taught tollhouses as literal. They ARE mentioned in the Liturgical texts and so should be considered a teaching of the Church. But what that means can be easily misunderstood. There are some "pious stories" floating around that are terribly misleading.
The most often way they are explained is this: demons tempt us (including trying to discourage us, lying to us, trying to entice us, whatever they think will work) throughout our lives. The process of death (which we should remember, sometimes takes some time, but even if it happens in an instant ... ) is still closely connected to life. It is the last chance the demons have to attack the soul, and it is also reasonable to think we may be vulnerable at that moment, since it is likely to be an unknown moment of some dread. Should we be surprised if the demons try one last attempt to terrify or entice the soul, whatever outcome they may be trying for?
I think it is better if we approach death expecting anything, yet hoping as always in Christ.
I spoke with a dear friend just today about an experience she had last year when she "died" but was resuscitated. It was very profound, and out of respect to her I won't recount it here. But she was very distressed about one thing. She is a Pentecostal-type non-denominational Christian, who loves Christ and lives for Him. But she expected only light, and was beyond distressed to find both light AND darkness present. I think it made her doubt her salvation, because of her expectations based on her beliefs. I explained to her very simply that I thought it was only a last-ditch "temptation" no different from what we experience all during life, and she had tears in her eyes and agreed that it made sense with all she was describing. Glory to God, I think, I hope, I was able to offer her some reassurance. Because to be honest, it seems she has been living in some fear of death since then, and according to her beliefs, there is no way she can become "more saved" than she already is. I can't imagine such angst, so I hope it really does help her to understand it in this way.
But literal houses in the air, manned by demons, extracting payments, judging the soul, etc? No ... we simply are as vulnerable to temptation to any earthly sin/passion we may have developed an attachment to during life, and we can expect demons to make attempts of any kind upon us until we are safely beyond their influence. This is the teaching of the Eastern Orthodox Church, as far as I've ever heard it (and I've heard it from a number of teachers and priests)
