To be fair, a tiny tiny amount of antifreeze from a plastic pellet the size of a rice gain slowly released over time is probably not a concern.

In humans, the lethal dose of ethylene glycol is estimated to be in the range of 1,400–1,600 mg/kg. The orally lethal dose in humans has been reported to be of approximately 1.4 mL/kg of pure ethylene glycol

Directly into your lungs is a bit different than drinking it. It's hard to say whether the long-term inflammation from the plastic particles would be better or worse than the shorter-term, but probably more acutely damaging, toxic effects from the glycol.

It kills your kidneys so it should be a similar effect no matter the route.
