$\begingroup$ I agree with all this. You could also try a Gamma GLMM with a log link (which should generally give fairly similar answers; the implied mean-variance relationship is the same as for a log-transformed LMM). One thing to be careful about with a log transformation (or link) is that it changes the meaning of the interaction; that is, an interaction on the log scale measures deviations from proportional (rather than additive) effects of the main predictor. The marginaleffects package may also be useful here. $\endgroup$
