    From the photo, the holes in the older leaf and the chewed leaf margins appears to be from a caterpillar or snails. Was the plant outside previously where it could have been exposed. If so, maybe the problem is no longer a factor.
    Try to identify what the pest is. On a small plant you can sometimes pick off a pest, or take it outside or in the bathtub and wash it off, and not have to spray.

    Neem oil is a preventive repellent for insect pests but may not affect snails.

    Hass avocados have a chance here in Tennessee, but It would have to be mature to be planted. It would also need a second tree. They are either male or female, so You will need to find out what sex your tree is and get a matching tree of the opposite sex.

    Most avocados will not grow here, and will die with the first winter. There are VERY VERY few avocados that will survive in TN, so make sure that yours is one of those before you plant it.

    They will all likely give fruit in the fall. Any pollinator will work, and you are correct. That variety will be one of your best bets. Mexican Avocados are usually a little more tolerant of cooler temperatures.

    Can you send pictures? Is this plant in soil, or in water?

    This is definitely a fungal issue! Most likely Anthracnose. Do you know how this tree was propagated? Starting them with toothpicks is one of the most common causes of introducing infections, and they may not show until later.

    If it is no known how the tree was started, then it can be chalked up to an infection already present in the soil.

    I would recommend applying, both, Dolomitic lime and wettable sulfur to correct the issue. Unfortunately all old leaves will retain the damage until they drop, but after treatment, within a few weeks, you should start to see new unharmed growth.

    If this does not correct the issue, more drastic treatments may be necessary.
