Can confirm, you can skip all of Llama Tea's dialogue, and you literally miss out on nothing. Worst character they've ever forced on us.

Some say she's Lyse better written, but Lyse was far more mature in a rather mature storyline overshadowed by better characters. Llama Tea gets 85% of the screen time and dialogue boxes, including many dialogues that you can't Enter/X your way through, and her growth amounts to a campfire scene where she gets told to be more mature, and then decides to be more mature... without actually changing at all.

The Role quest NPCs actually experience more growth with a thicker plot in five role quests than Llama Tea does over the twelve dozen or so she's in.

And they force the WoL to warm to her without the player's opt in, as if she were as charming as Aphmau from FFXI or something. Ridiculous.
