    Yes, this could definitely be the issue. Treat the tree with neem oil, which will kill the pests and is an effective fungicide too. In addition, you may want to contact an arborist (tree expert) if the tree doesn't show signs of improvement.

    If the bark has split clear down to the interior wood, then it needs to be sealed to keep insects out and prevent disease. There is a tar like product called Tree Wound Sealer on the market. Most garden centers have it. I believe ACE hardware carries it as well. Apply such a product to the split working it well into the split. Once done sprinkle it lightly with a fine sand to help make it less sticky, thus it will stay in place better if anything brushes against the treated area.

    No, you can remove the suckers anytime without causing harm to the tree.

    While the American elm is considered somewhat allelopathic, the shade it produces is far more inhibitive on other plants than chemicals produced by the tree. This article has some information on elms: https://www.gardeningknowhow.com/ornamental/trees/elm/growing-elm-trees.htm

    Are you saying that when you went out of town the tree wasn't watered? Generally, we expect to water newly planted trees only once a week, deeply. So, it's possible that the soil around the roots was too wet, thus unable to oxygenate properly, and the roots were damaged. As long as the tree is not dead, there's always hope. You might try digging down around the rootball to actually feel the condition of the soil; it should not be muddy or sopping or soaked, but damp and cool. Here are a couple of articles on elms in general, and drakes in particular: https://www.gardeningknowhow.com/ornamental/trees/elm/growing-elm-trees.htm

    I would certainly agree that the dry conditions are and will effect your trees.
    Lessing leaves is most certainly a sign of stress.
    Here are some links for you.

    Cut the tree seedlings and paint the fresh cut with undiluted Round-up. The fresh cut will cause the plant to pull the Round-up into its system and will kill it. You may need to repeat 2-3 times if the roots grow deep, but it will work.
