Is anyone aware of a way to calculate log-likelihood for GEE models?
No. GEE fitting is based on quasi-likelihood.
However, it is possible to derive AIC-like measures based on the
quasi-likelihood. Lebreton et al (1992) suggested a simple adjustment in
the GLM

For GEE models, Pan (2001) has introduced QIC. None of these measures are
implemented in R or in any add-on package as far as I know.
Actually, take a look at
