Not so fast here:
We find some very strange language both here and other places that doesn't sound like human kings. We must be sensitive to the cultural style of writing in Ezekiel and Isaiah.
In Ezekiel 28 we see a lament to an earthly "Prince" the "Prince of Tyre"
but then in verse 12 we see:
12You were the signet of perfection,
a
full of wisdom and perfect in beauty.
13You were in Eden, the garden of God;
every precious stone was your covering,
sardius, topaz, and diamond,
beryl, onyx, and jasper,
sapphire,
b emerald, and carbuncle;
and crafted in gold were your settings
and your engravings.
c
On the day that you were created
they were prepared.
14You were an anointed guardian cherub.
I placed you;
d you were on the holy mountain of God;
in the midst of the stones of fire you walked.
15You were blameless in your ways
from the day you were created,
till unrighteousness was found in you.
16In the abundance of your trade
you were filled with violence in your midst, and you sinned;
so I cast you as a profane thing from the mountain of God,
and I destroyed you,
e O guardian cherub,
from the midst of the stones of fire.
17Your heart was proud because of your beauty;
you corrupted your wisdom for the sake of your splendor.
I cast you to the ground;
I exposed you before kings,
to feast their eyes on you.
18By the multitude of your iniquities,
in the unrighteousness of your trade
you profaned your sanctuaries;
so I brought fire out from your midst;
it consumed you,
and I turned you to ashes on the earth
in the sight of all who saw you.
19All who know you among the peoples
are appalled at you;
you have come to a dreadful end
and shall be no more forever.”
Now do you think the King of Tyre was in Eden the Garden of God?
Was the King of Tyre a guardian cherub?
Was the King of Tyre on the mountain of God?
Did God bring fire out from your midst of the King of Tyre?
As for Isaiah 14:
Joseph Jensen writes the following, "The taunt-song is a magnificent composition, rich in imagination and allusive force. The question of Isaian authenticity is closely bound up with the identity of the figure against whom the taunt is directed. The background from which Helel comes, as depicted in vv. 12-15, is variously given as Near Eastern mythology or astrology. The pattern found in patristic texts is largely that established in those already examined. For the most part Isa 14:12-15 is either interpreted directly as Satan or as the king of Babylon, as merely a cipher for Satan." (Helel Ben Shaḥar (Isaiah 14:12-15) in Bible and Tradition,
Writing and Reading the Scroll of Isaiah, Volume 1, pp 339-356)
Dr. Michael Heiser demurs, "Many scholars of the Hebrew Bible have postulated that the source of the taunt-song of Isa xiv 12-15 is to be found in Ugaritic religious literature Many of these scholars believe that the passage contains elements of both El and Bac al myths, an assumption that leads them to discount the proposition that all the mythological strands of Isa xiv 12-15 can be correlated with a single Ugaritic myth Still others contend that only a single myth concerning the usurpation of El can account for all of the mythological features This article disputes both of these positions, arguing that no usurpation of El is in view, and that the mythological provenance of Isa xiv 12-15 can be entirely correlated with the Ba'al-Athtar myth."

It is unclear exactly what these sources are but an earthly king is not the focus. Ba'al happens to be the individual that Jesus calls Beezebul or
BaʽalZebūb "Lord of the flies."
However, to your point your willingness to be skeptical of a proof-text is laudable.
Your attempt to look at them in the cultural context is also correct, rather than jumping to a conclusion.
If we are going to study Satanology, we certainly have to do it inside the older babylonian texts that appear 800 to 1000 years before the OT.
