I have dissected a scots pine that had ivy all over the ground . The tree
was the healthiest scots pine I have seen.
So some trees may be companion plants and some not. Again, other than
blocking sunlight from needles and leaves I know of no published research
showing that ivy kills trees. I personally do not like ivy growing on
trees. The reason is because it covers up defects and signs of a high risk
of hazard situation such as cracks and so on.

Does anyone have data (peer reviewed published papers) showing that ivy
kills trees. I would like to read it and place it in my dictionary for all
to read under hard to get docs.

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.

I hope you don't like those large pine trees, because they'll be dead
sooner or later from the ivy.

Do you have the data that the ivy will kill a pine tree. I really know
of no data to establish that as a fact.
Sure it can block leaves and needles for photosynthesis. Other than that
what are you talking about?
