Cute paws
…I think those spots look like septoria — a fungal disease.
Cut off all the leaves below the fruit truss, leaving about 1/2 of leaf stem on the trunk. (These will dry up and fall off on their own)
The leaf opposite the fruit truss can be cut off too — I’m following this protocol after watching Japanese gardening videos that said this leaf can divert calcium from the developing fruits, and removing it soon after fruit set can help prevent BER (blossom end rot).
Start spraying your tomato plants to prevent fungal disease from getting foothold. At least once a week, twice a week is better, alternating between biological and chemical.
I prefer 1:8 diluted milk and whey in de-chlorinated water, or 1:10 AACT (actively aerated compost tea), or 1:200 eggshell vinegar {crushed eggshells steeped for 24~48 hours in grain (rice) vinegar -then strained into a glass storage bottle-} for biological. …And potassium bicarbonate 1Tbs in 1 gallon with a dribble of liquid soap and few drops of oil (canola … this year using neem supplemented canola) for chemical. Baking soda (sodium bicarbonate) can be used instead and is more common recipe, but spending for potassium bicarbonate will add potassium as foliar supplemental nutrient).
I also spray peroxide (dilution?) directly on fungal spots if I’m trying to keep the leaves, but more likely to clip off affected leaves.
