fruitz:

does anyone know what the deal is with this leaf on my philodendron? it was there when i bought her. i thought it looks like sunburn but the leaf is otherwise healthy and no other ones are affected! theres also a little hole in it so maybe a bug chewed it? does it look like an issue?

Keep watch that the soil isn’t oversaturated lest its a root health issue, remove the leaf if it doesn’t bounce back and just check if in the future if any leaves develop similar symptoms. Otherwise I’d say it looks fine. Every houseplant occasionally has a few iffy leaves develop here and there, so long as fresh leaves replace said leaves to replace the lost ones.
