Yes. In some cases, "Undefined" is the best answer to the question. Remember that your operation (exponentation, or the 'power' of a number) is under the 'Rules', called axioms, of the field of Real Numbers. Your question has an infinity, which is not a real number, so it's not a surprise that things don't work out into a normal answer. In some cases, problems with infinity can be better understood through limits. An expression like "1 / infinity" is also undefined, but the limit (as x approaches positive infinity) of 1 / x is equal to zero. But in this case, there isn't even a limit: there is no amount or number that (-1) ^ infinity "converges to". Answer from CatOfGrey on reddit.com

Limits to Infinity
It is a mathematical way of saying "we are not talking about when n=∞, but we know as n gets bigger, the answer gets closer and closer to the value of e". If we try to use infinity as a "very large real number" (it isn't!) we get: ... So don't try using Infinity as a real number: you can get wrong answers! Limits are the right way to go. I have taken a gentle approach to limits so far, and shown tables and graphs to illustrate the points. But to "evaluate" (in other words calculate) the value of a limit can take a bit more effort.

Infinity is undefined so in a sense you've answered your question. This is like asking what is (-1)^apple when there is no definition of a value for "apple". This is not a put down, you are asking for an explanation what happens when one performs an operation on an object that the operation isn't defined for. I believe that there are mathematicians who try to extend the ideas of infinity and how certain operations work by applying these ideas. But this would be the realm (I suppose) of PhD abstract maths.

Solving 1 Divided by Infinity - The Story of Mathematics - A History of Mathematical Thought from Ancient Times to the Modern Day
March 21, 2023 - Solving $1/\infty$ is the same as solving for the limit of $1/x$ as $x$ approaches infinity, so using the definition of limit, 1 divided by infinity is equal to $0$. Now, we want to know the answer when we divide 1 by infinity, denoted as $1/\infty$, which we know does not exist since there exists no number that is largest among all. However, if we will use the definition of a limit of a function and evaluate the function $1/x$, where $x$ becomes larger and larger, we will see that the function $1/x$ approaches a particular number. The following table, Table 1, shows the value of $1/x$ as $x$ gets larger and larger.

Calculus I - Limits At Infinity, Part I
In this case the indeterminate form was neither of the “obvious” choices of infinity, zero, or -1 so be careful with make these kinds of assumptions with this kind of indeterminate forms. The second limit is done in a similar fashion. Notice however, that nowhere in the work for the first limit did we actually use the fact that the limit was going to plus infinity. In this case it doesn’t matter which infinity we are going towards we will get the same value for the limit.

When I was really little, my older brother and I were messing around on the calculator.( i was like 8 so he was prolly 11) then he said "hold on, watch this" he typed some random shit in and the answer it gave was infinity(symbol) fast forward 10 years later and I thought about it, does anyone know what he could have typed in? Im 90% sure it was on a phone/ipad calculator

Could have been using any calculator app. There are a bunch that can do symbolic calculations. Symcalc was a pretty comprehensive one that was for Apple around that time.

On many "smart" calculators of that era, entering a high enough number will cause the calculator to return "infinity" due to it being outside the range of numbers it can display. Modern "smart" calculators now simply tell you that it can't perform such a calculation.
