The act of recording was illegal in Florida where it was done. The criminal and civil action for the illegal act of recording, and damages for anyone using the illegal recording would be in Florida.
In most states, the law holds those who use the illegal recording as also liable criminally.
Trump did not (we are told) call a Florida telephone number and Fuchs was not a party to the call and did not direct the course of the discussion. Moreover, what if the phone Fuchs used for the recording this business call while she just happened to be in Florida was her GA state issued business phone with of course a GA state number?
A significant GA state interest is at risk by simply moving Fuchs a few feet across the border. 1 party state callers who wish to exercise their recording rights would now bear the burden of knowing the exact location of every party to the call before recording. {;^)
