The exact opposite is true.
Stranded wire is always worse for higher frequencies, and lightning
has considerable high frequency energy.
Stranding (or worse yet weaving) is undesirable even with pure dc
with extremely high current flows.
Stranding is better if the wire has to be bent in a tight radius or
if it must be flexed many times.
