I don't think it's about understanding. Lawyers are pretty smart. But there's no upside to you as a corporate lawyer if you advocate for taking risks. Even if you think you're on solid legal footing, you're going to miscalculate sooner or later, or run into a hostile regulator. And then, it's on you.
Conversely, there's no real downside to being too conservative, especially if engineers and leadership are entirely deferential to you because they don't understand your field (or are too afraid to speak up.)
Although this is also somewhat true for security, privacy, and safety organizations, their remit tends to include "enabling business." A safety team that defaults to "you shouldn't be doing this" is not going to have much sway. A legal department might.
