This systematic meta-analysis paper[1] may be more convincing. The popular youtube COVID-commentating Dr. John Campbell did a review of it about a month ago[2] and has some good comments on the meaningful statistical power and experiment design.
The overall takeaway is this: in people with Vitamin D deficiency (which is very, very common), continuous daily supplementation can lead to up to a 70% reduction in contracted viral respiratory infections. It has a smaller effect the less deficient you are, and is not associated with any adverse effects.

Same here. Old people are less likely to get enough sunlight [0]. And old people are more likely to have severe COVID-19 symptoms.
Similar story with ibuprofen and COVID-19 [1]. Researchers found a link between the two. But older people are also more likely to take ibuprofen.

It's not even correlational. They didn't even have a group of non-COVID patients to compare to, which would have been really easy. They could have looked at non-COVID ICU patients as well and did not. That would have at least been correlational.

Perhaps. D has been long known to support the immune system however, including respiratory ailments. More study needed.
i suspect VID correlates well with COVID comorbidities, like a sedentary lifestyle, hypertension, and weight problems. the opposite is also probably true, that people with good vit D levels correlate with healthier lifestyles and fewer comorbidities.
