If you are truly interested in the Tollhouses as an issue, I can look for several special series of podcasts I listened to last year. I listened to them several times, tried to integrate that with everything I'd heard, then came here and asked lots of questions, and it all fell into place for me.
That's why I think I said earlier in this thread that it depends on WHAT you believe about them as to whether or not the Church agrees.
The Church does teach tollhouses, but a great deal of what you may find said about them is not what we actually believe in a literal sense.
I know now why my priest asked me to avoid reading about them too early on (he long since released me, but I was an inquirer at the time).
There is no widespread acceptance of the "Theodora" account in a literal sense. Even some of the things that account implies, as principles, are really quite problematic, according to several priests. I haven't read Seraphim Rose on the topic. If someone WANTS to believe in them in a literal sense, as far as I can tell, it would be allowed - as in you won't be excommunicated over it. But if you started teaching others it was completely literal, well ... I might guess your priest or bishop might have a word with you.
The most conservative and probably "consensus" approach I have distilled is this: Demons attempt to tempt, destroy, mislead, lie to us, etc. all our lives. We are always vulnerable to possible attacks by them, in whatever form the demons may attempt (by God's allowance of course). At the moment of death, the demons are seeing their last opportunity, and since it is an unknown experience for us, we are at risk to be greatly vulnerable to suggestions or experiences at that time. So it is very reasonable to expect a heightened "last ditch" attempt by the demons - to convince us God isn't real, or we've always been wrong, or God won't really forgive us nor we are too sinful, or to tempt us with those passions we won't be able to indulge anymore because we are losing our bodies, or, or, or ... So that whatever form it takes, we might expect it to be a most difficult moment. (I would say this is both a reason we pray for the dead, and also one reason we don't lightly assume anyone's salvation without proof from God after their repose - but those are my personal assumptions.)
I would say THAT is consensus about tollhouses, and meant to be believed. After all, the Church desires that we exoect this onslaught, so that we can be prepared for it.
The further you go from this, the more literal your understanding, the more - questionable? - it all becomes?
There are of course the numbered toll houses mentioned that deal with various passions/temptations/sins. But IMO that is simply a device that reminds us, when we contemplate these things to consider EVERY possible thing the demons may find in us, so that we can deal with it. I am reminded of the Ladder of Divine Ascent, which also includes numbered and named rungs of virtues. That doesn't mean there is a literal ladder, but it is a way of helping us to think of how these virtues build on one another, how we might typically progress through them, and to be reminded to think of them all.
In this way, the non-literal aspects can be "true" but not literal in the sense of actual physical buildings in the sky manned by demons that we must pass through in peril.
It was something I struggled a bit with, so lmk if you want links to those podcasts and I'll look for them. They weren't all about tollhouses, but about the afterlife, the eschaton, death, etc. but tollhouses did get referenced and explained there. It is overall quite a few hours of listening though. But gives a very good overview of these kinds of topics as a whole.
I do remember when I mentioned it at first to my priest (just one of them) his response was something like "how did they teach for seven hours on the afterlife - we don't know THAT much?" But it really is an interweaving of many related topics.
