DY, see Rashi on Lo Yaakov. he brings the pshat in Hoshea 12:5. clearly the Novi Hoshea and Rashi see it as struggling and prevailing. Also the Sifsei Chachomim citing the Gemoro in Menuchos describe it as the malach of Esav who he was struggling with and prevailing over. So, yes, if you want to say “Yisramalach” or “Yisramalcho”, you can I suppose, but the pshat says Yisrael.
And, DY, I’m not looking for readers here to understand it the way I do. I was simply explaining my own perspective.
I appreciate your being don l’kaf zchus of ITFT, but even if I saw the second last line as general, the last line can’t be understood any other way.
