Some players, including Brooks Koepka, have returned to the PGA Tour, which rewrote its rules in December to allow the five-time major winner to come back, subject to certain sanctions, including making a $5m (£3.7m) charitable donation as part of his return.
However, the American-based circuit closed its returning member programme on 2 February with Rahm remaining under long-term contract with LIV.
However, in May, he reached a deal with the DP World Tour to retain his membership of the European circuit and remain eligible for next year's Ryder Cup.
LIV golfers are automatically banned for a year by the PGA Tour. The DP World Tour offers a pathway and the leading 10 players currently gain access to PGA Tour membership.
"Brooks was able to go back through certain circumstances," said Rahm. "I don't know if the possibility of that would be open for me or not.
"But if I have to fulfil a one-year suspension, I think it's a pretty good position to be that a worst-case scenario I get to play on a wonderful tour [DP World Tour] for a whole year."
Rahm added: "I seriously doubt I get offered the same deal that Brooks did, but if I got offered exactly the same penalties as him, I probably would do it, yes."
