I think that Glysophate on the Ivy will take care of it. It is a systemic and a small amount on the bark won't hurt. If you are really concerned, take a small paintbrush and paint it on the Ivey leaves.

If they're that big, use Remedy (a.i. triclopyr). Do not use Remedy on smaller trees because it will travel (volatilize). First you will need to cut any vines that are climbing up the trees beyond the point at which you will be spraying.

i've sprayed 2,4-d amine on poison ivy around large oak trees with no problems that i know of. but in the heat may volatilize.
