Hey there im sure the transplant shock is a factor with the torn roots, but being photoperiod plants they should have time to pull through and build new roots and any damaged leaves. I think your low night temps will help keep them small and once it rises they'll definitely flourish more. Perhaps laying a blanket or other garden type cover around the base of the plants at night will help keep them warm, also the cup over the top in the evening into the night would help also, if there's holes in the cup it won't trap too much humidity.
Bugs were a constant battle for me outside, if you can buy a basil plant that's a good companion plant to deter bugs, rosemary is another good one. It's also nice to turn some lady bugs loose, pirate bugs and hatch a few praying mantis(i think they're good with caterpillars etc), and if you see wasps near by let them have free reign as they're incredible killers.✌️ Happy growing.
Oh p.s. if you can add a silica product to your feedings that helps the plants resilience and strength for fighting off the various outdoor battles.
