If this product title is already present within the page (maybe as an
image caption), then it probably not make sense to also add this as
the image alt attribute value as it would then be redundant and read
twice by screen readers.
It sounds like "closest we can get" is merely a reflection of
limitations of the current system. Certainly there must be a mechanism
for somebody to provide alternative text for such an image somehow,
no?

Best guess doesn't sound very good. If the content of the image is
conveyed in content, then give it alt="" (assuming it is not the only
thing inside a link, in which case it *must* be given alternative
text, even if it is redundant). Barring that, my first suggestion
would be to fix the system to allow appropriate, descriptive
alternative text.
Alt=" " (quote, space, quote) is never appropriate.
