Lillie would be the first person we see to mess up the first lesson everyone should know when it comes to capturing Pokémon.
Over-exaggeration shouting, extreme emphasis on throwing, striking a pose, I'd argue the reverse
Don't think we've seen (or at least, Lillie's seen) anyone other than Kiawe release a Pokemon from a Pokeball (onscreen at least). Maybe she took her cue from him throwing Turtonator's ball in the air.
EDIT: I just remembered that she also saw Rowlet vs Oricorio. So...maybe not.
