No, but there is a extremely uncomfortable scene where a male character starts to droll and chokes a much weaker female character in a bed while in top of her.
Technically no but there is a character the player can romance that looks very young even though she isn't and the flawed affinity system means the player can accidentally end up with children as their beloved which makes a few cutscenes in the game very questionable. Nothing explicit but definitely a little weird and more than a little gross
Thanks to the affinity system and the game being gender neutral, everyone in the game is functionally bisexual and people do die, but no specifically LGBT+ people die
One side quest does have the player dress as a women if the player is male and there's an achievement for it as well, but it isn't so much a joke as it is a game mechanic to get past an NPC who hates men
The player and their party can be possessed by phantoms and phantasms, also dragons can take control of the player's party and force them to fight the player
