Yes, green and poisonous

We don't earth up, we don't get significant numbers of green spuds, only
the odd one that pokes out of the ground. Even then only the end out of
the ground will be green.

Yes, green potatoes may be toxic - not he green-ness, - which is just
chlorophyll but they can also contain Solanine which is what gives them
toxicity. However, you would need to eat an awful lot of green potatoes
to suffer from it. Anyway it's easily peeled/cut off.
