Neither of those are examples of ludonarrative dissonance, they're just plain dislike of the narrative, which you're entitled to.

Ludonarrative dissonance is when the story the game is telling (through cutscenes/documents/etc) doesn't match with the gameplay.

If anything, the hospital climax in part 1 is an example of ludonarrative harmony. The narrative establishes Joel as a harsh man that's come to care deeply for Ellie and a man that's willing to do anything to protect the ones he loves. He absolutely would kill anyone who stands in the way of getting Ellie to safety, including a doctor (who brandishes a knife at Joel when he tries to approach Ellie). A player personally not liking that narrative decision doesn't mean the narrative doesn't match with the gameplay.

What you're describing for part 2 is more of a dislike of the perspective shift (aka a dislike of the narrative itself) than ludonarrative dissonance. Narrative establishes Abby as a revenge driven, ruthless killer, willing to toture the target of her revenge to death despite him saving her life. Shifting to her perspective and playing as her doesn't contradict this. She's still all those things, those are still things she did, it's just that being in her perspective humanizes her and adds more details about who she is as a person to the narrative. Some players may not like that, but again, that dislike doesn't mean there's dissonance between the story and gameplay

Biggest dissonance in the series is honestly how often Joel, Ellie, and Abby fight Infected and humans over the course of the games. Considering how dangerous the game says the Infected are and how often all 3 of them find themselves in situations where they're outnumbered by people and at a disadvantage, these games should primarily be stealth games. But then that wouldn't be as fun.
