The olives are used by mammals and many birds like turkey, quail, pheasant, robins, waxwings, mockingbirds and more. Russian Olive is also attracts insects which bring in warblers, finches, etc. There are shelterbelts all over eastern and western CO that are full of wildlife principally because of Russian Olive and other berry producing plants sold to ag land owners by the State Forest Service.
The thorns are nasty for sure which is why nobody wants wood chips from them. I've had many tractor tire flats from the thorns. But, Russian Olive on my property are not invasive, they only grow where I plant them, and I'm not taking them out.
