李德裕
李德裕 appears in 76.玄怪录：晚唐党争？没耽误宰相写大马猴的故事 as the “Li” pole of the 牛李党争. The episode contrasts him with 牛僧儒 and 李宗闵 while explaining the late-Tang political background behind 《玄怪录》.
The source uses Li Deyu most concretely in the Tibet/Tubo policy contrast: he is associated with the more assertive line of accepting a rebel general and considering military action, while 牛僧儒 argues from alliance obligations and the cost of renewed conflict. The page remains source-scoped rather than a full political biography.
90.酉阳杂俎：血滴子和武则天手指上的黑毛 adds a lighter 《酉阳杂俎》 connection: the episode names Li Deyu among 段成式’s literary-political circle and says he appears repeatedly in the book’s material field. This extends his page only as a source-context link, not as a new biographical claim.
