Firstly, the interviews you are referencing were part of an article and retrospective in
The Comics Journal #50 (1979) and Fantagraphics Books' 1982 volume
The X-Men Companion [TXC], respectively. Both interviews were referenced in
Back Issue! #54 (2013). I have copies of the latter (i.e.,
Back Issue! #54), which I will post relevant scans of below, and will be getting access to the former (i.e.,
The Comics Journal #50), though I also have the relevant quotes from that article on hand and will share a link to them below. As for
The X-Men Companion, I am in the process of searching for it.
Now that clarifying the sources is out of the way, neither Claremont nor Cockrum ever stated or implied that "Jean was given Phoenix to put her on the power levels of Ororo." In fact, Claremont made quite the opposite clear: Phoenix was meant to be the X-Men's
first female cosmic superhero. (NOTE: There is some evidence that suggests she was actually Marvel's first female cosmic superhero, but I'm still researching that.) However, after he was met with resistance from the editorial staff—they weren't keen on having a female cosmic superhero—he was
forced to reduce Phoenix's powers to Storm's levels. In
The Comics Journal #50 (this is referenced in the
Back Issue! page posted below), Claremont admitted:
Not only does the above quote confirm that Jean/Phoenix was intended to be the X-Men's first female cosmic superhero—again, I'm not yet sure if she would've been Marvel's first—but it also makes it implicitly clear that, at the time, Storm was not considered a cosmic superhero. Additionally, during the same interview for
The Comics Journal, Claremont continued:
He also expounded:
(NOTE: As I noted above, the last two quotes from
The Comics Journal are not included in the
Back Issue! article. Instead, a quote from
The X-Men Companion is referenced. As soon as I get access to the direct scans of
The Comics Journal article, which should be within the next 1-2 days—I subscribed to their archives subscription—I will post them, too. Here is the source for the last two
The Comic Journal quotes:

Frankly, the above quotes speak for themselves. Now, the quote from
The X-Men Companion, which was published in 1982—three years
after The Comics Journal interview above—and referenced in the second
Back Issue! page posted below, is as follows:
In the quote above, Claremont claims that he and Cockrum had "originally envisioned that [Jean/Phoenix] had a power level...equivalent to Storm's," which slightly contradicts what he said three years earlier when he noted, "We had to cut [Jean/Phoenix] back. So we decided to cut her down to roughly where Storm is." In either case, the same applies: Not only was the creation of Phoenix not influenced by Storm but Jean/Phoenix at her full potential was considered more powerful than Storm. Moreover, Jean/Phoenix's M'Kraan Crystal feat was meant to showcase her abilities at their fullest potential, which Cockrum confirms, substantiating Claremont's claims above:
In either case and to reiterate, it is clear that
the introduction of Phoenix was 1) not influenced by Storm's power levels; 2) meant to be the introduction of the first female cosmic superhero; 3) meant to represent Jean's full potential as a psi; and 4) was conceived as being more powerful than Storm.
Before I share the
Back Issue! pages, I also want to note the following: Jean was categorized by a highly-advanced, bio-sensor-equipped A.I., which were not prone to hyperbole at the time, as having "infinite mental powers" in Uncanny X-Men #48 in 1968. Incidentally, in that same issue she was able to use her telepathy to psi-scan and track an "electronic [robot] brain," which was unheard of then and is rare even now.
This was all nearly a decade before Claremont became the writer for X-Men and introduced Phoenix, or as some of you so affectionately refer to it as: "the burnt chicken." I point this out to underscore the fact that Jean's abilities being referred to as "infinite" far predates Claremont and his Phoenix stories. In fact, I wouldn't be surprised if this is why Jean, as Louise Simonson noted, was his "total favorite." (Here is the video source for Simonson's quote:
