I don't think you're going to find this level of detail for a variety of reasons...but, let's start with the premise. The overtaxing of hospitals was much more salient rationale before the vaccination campaign was launched, which gave a lot more breathing room and slack capacity for hospitals. When hospitals were overrun in places like Bergamo and the whole city was sealed off, it would be hard to imagine why tourists should be at the forefront of minds of people who were barely treading water (they weren't even tracking the deaths of segments of their own population accurately but did the best they could, I'm sure many of the figures were imputed). Now, there is worry about the delta variant and covid economic after-effects which also make it unlikely that you'll see prioritization of aggregating data on non-citizens (assuming it's being tracked accurately in the first place).
Historical data on general, pre-covid injuries and deaths is uneven and periodic. Most injuries and fatalities were caused by vehicular travel, ski accidents, drownings and the like. Data for selected countries and limited time periods was collected, such as this piece of research: https://ec.europa.eu/health/ph_projects/2001/injury/fp_injury_2001_frep_10_en.pdf. Getting data aggregated for all of Europe would be an enormous undertaking (think just about the reporting anomalies between well-resourced and non-well-resourced countries)....if it hasn't been done up until now on general injuries, it's doubtful you will find covid-specific data now....perhaps it will be there one day, but there is always a few years data lag on any substantive research (we are not through with the pandemic to look at it retrospectively yet, anyway).
In 2005, a very general estimate of 3,800 deaths of tourists was made (doesn't even differentiate between US and non-US tourists), so maybe that gives you some perspective. https://pubmed.ncbi.nlm.nih.gov/15814378/
