Exactly. At best, this is a YMMV Audience Reaction
of "Dude, that guy needs help!"
Things failing to happen in a story that a reader thinks should have happened are not a trope. Just a difference in opinion between the writer and the reader as to what is relevant or appropriate for a given story.
Also, I've seen far tpo many stories that do include therapists in one way or another to think that this is necessary the norm in in story telling.
Creators mention therapists when they feel like it and don't when they don't, but there is no pattern, story telling device or convention saying that therapists are taboo.
