I don’t know about how this would impact the estimates, but the Pacific Northwest differs from Japan in that the largest population centers — Vancouver, Seattle, Portland — are not exposed to the open ocean.

Seattle also rises very quickly from the ocean. Take a look: https://en-us.topographic-map.com/maps/na3/Seattle/
With the exception of the international district, all the low-lying areas are industrial in nature.
"Drumlin" is the fun word for this geology, from what I understand. https://youtu.be/oSSxdogrv1s?t=189
Right, in Oregon the coastal areas mostly rise quite quickly from the beach and are relatively sparsely populated. The more populated areas of Portland, Salem, Eugene, etc are well away from the ocean, so a tsunami is unlikely to kill very many people here.
