You should only run the queries when they are visible for the user to avoid running multiple queries at the same time....
The "Rate limit exceeded" is definitely a rate limit issue. Making sure the requests are sent serially would certainly help. Just running them when the related <div/> is visible is probably good enough, and would most probably reduce the load on the WDQS servers.
Looking at the requests made from https://tools.wmflabs.org/scholia/author/Q8219, I see that at least some of the requests generating an HTTP 500 seem to have a syntax issue, leading to a java.lang.IllegalArgumentException: Non-aggregate variable in select _expression_: work. Those request should result in an HTTP 400, but that's probably non trivial to fix on our side. @Smalyshev might have an idea to fix the HTTP status, but the root issue seems to be the query.
