There are numerous studies that show glyphosate binds with aluminum and other metals, having negative impacts on public health.

That first paper you cited is kind of a running joke. ScienceBasedMedicine ran a whole article on Seneff's work:

It's based on a Rube Goldberg causal mechanism and a slapdash correlation analysis that vibes glyphosate as the presumed cause of sleep disorder and autism diagnostic increases over the preceding 20 years --- glyphosate went up, autism went up, what more is there to say?
A later review of the literature on glyphosate went out of its way to exclude it:
