Does the "learned" in "learned helplessness" refer specifically to behaviorism's conditioning?
Wikipedia explains that there's not one theory of learned helplessness but several, some more encompassing than others with respect to what is learned:

Research has found that a human's reaction to feeling a lack of control differs both between individuals and between situations, i.e. learned helplessness sometimes remains specific to one situation but at other times generalizes across situations.[7][9][10] Such variations are not explained by the original theory of learned helplessness, and an influential view is that such variations depend on an individual's attributional or explanatory style.[11] According to this view, how someone interprets or explains adverse events affects their likelihood of acquiring learned helplessness and subsequent depression.[12] For example, people with pessimistic explanatory style tend to see negative events as permanent (&quot;it will never change&quot;), personal (&quot;it's my fault&quot;), and pervasive (&quot;I can't do anything correctly&quot;), and are likely to suffer from learned helplessness and depression.[13]

(Aside: contra to the somewhat one-sided way in which Wikipedia discusses this, the expanded theories were not that easy to demonstrate reliably, at least not with a sizeable effect.)
