What is L_square? Is it Likelihood ratio/deviance statistic which is reported by poLCA?
The predcell component contains observed and expected, isn't it easy to get the residuals?

If you want the logit/logistic model, glm or lrm (rms) can do the job.

It is unrealistic to expect different software report the exact result, though most of them report the most important and basic statistics.

For example, I would create latent class solutions for each gender based on four dichotomic indicators of psychosis. Next, I would look at the interaction of current psychiatric status (the classes) and past psychiatric diagnosis to predict institutional treatment use (logit or logistic models). poLCA is a little limited for this purpose; I would have to use it in combination with some other package. For example, it doesn't provide residuals for the indicators, or the Cressie-Read statistic.
