Quickly looking at her CSAIL page, I note 2 things about her glyphosate research:

(1) Her talks generally are not at scientific conferences.

(2) Her published articles are in "predatory open access journals". Since she is not stupid, I assume she is publishing this work there because she cannot publish in more respected journals.

The WHO is respected, it is relying on well-performed studies. If they say glyphosate is probably carcinogenic, I'll pay attention. Seneff is publishing in Omics and MDPI journals, which are viewed as publication mills by the community. It appears the community has examined her claims and rejected her from being publishing them anywhere respectable.
