Are there practical applications of any these problems being solved? No judgement implied, I'm well aware that "no" only means "not yet".

The big impact will be with scaling, for example complete autoformalization of existing math, and automatic exploration for new conjectures, with emphasis on how interesting they are. Automatic conjecture generation goes way way back, to the days of Lenat's AM system. Modern AI should do a far better job.
To answer your question directly: most Erdős problems don't have practical applications on their own; the value is the techniques and the machine-checked proofs they leave behind. But there's more real world value in solving some of the FrontierMath Open Problems or Millennium Problems. There's a Venn diagram of "hard problems" and "real world impact" for sure.
